Car Shakes At Idle But Smooths Out While Driving – How To Fix This Problem?

Published on: 09 February 2023 Last Updated on: 04 September 2024

You might have noticed some irregularities with your car, like how it’s vibrating more than usual, even while idle. This can happen due to many reasons. Therefore, people should know the reasons behind why their car shakes at idle but smooths out while driving.

If you are looking for the answer to this question, then you have clicked on the correct link. In this post, you will learn why the above effect happens and what needs to be done to solve it.

Why Does Car Shakes At Idle But Smooths Out While Driving And How To Fix This Issue?

If you wish to know why your car shaking while idle, then there can be various reasons for this issue. Therefore, here are some of the most common reasons why your car shakes when idle:

1. The Motor Mounts Are Weak

As you already know, your engine is stored in the car’s engine compartment. This is done with the help of motor mounts that are attached to the engine to keep it in place.

When these mounts become weak, they might fall off one by one. This can create a situation where your car vibrates when idle. You can notice this the most when your car is in neutral.

If it does so, then you better go to a mechanic to get it checked and fixed immediately.

2. Damaged Spark Plugs

Spark plugs are connected to your engine and are responsible for igniting the fuel that goes in it. However, after lots of use, these spark plugs can become greasy due to the accumulation of residue from burnt oil. This can cause the engine to misfire.

Therefore, it’s best to keep in mind that your spark plugs are best replaced after every 20,000 to 30,000 miles. However, if you have a car that has a diesel engine, then there’s no need to worry about this since diesel engines don’t have spark plugs.

3. The Camshaft Timing Chain Is Loose

Many cars have a camshaft timing chain, which helps all the camshafts stay attached to your engine valves and pistons. This can create a problem for you if the timing chain for your camshaft has a loose chain tensioner.

If you don’t get all the hoses of your engine inspected by a mechanic, then your complaint about your car shaking when idle will never cease. This is because it can cause an engine vacuum leak, increasing the pressure inside its cylinders and vibrating your car.

4. Battery Cables Are Loose

Another common reason why your car shakes at idle but smooths out while driving is because of loose battery cables. If you see your car wont start after getting gas, then this might be one of the reasons why.

This can happen if you recently changed your car battery. It can happen if the battery is not correctly connected to the battery cables. After driving around town, there is a chance that your battery cables might become loose, which leads to vibrating cars.

5. The Sensors Are Dirty Or Worn Out

Two primary sensors in your car that are essential for starting it up are – the throttle position and oxygen sensors. Since they are located so close to the engine, they get greased up over time, making them malfunction.

Adjusting the throttle cable a bit too tightly might cause the car to turn even while idle. Also, it makes things rough while driving as your car might speed up irrationally at times.

In the same vein, a dysfunctional oxygen sensor can lead to exhaust malfunctions. This can also be another reason why your car shakes while idle.

6. Faulty Ignition Control Module

Your car’s idleness can be disturbed if there are faults in the ignition control module. Here, your engine might not start since the control module wrongly sends a signal that makes your engine misfire the compression from your cylinders.

You can quickly diagnose this problem if you see your car vibrating on idle, even when you are not pressing the accelerator while in gear.

7. The Gas Cap Is Loose

One of the most common causes of your car shaking on idle is a loose gas cap. If the gas cap is loose, then air can leak inside, pressuring and vacuuming the engine even more. This increase in pressure can cause your engine to shake, even while the car is idle.

Therefore, try checking your fuel cap. Open it yourself and then put it back. If you see the cap is loose, then you have found the main culprit.

8. Malfunctions In The Fuel Intake System

If you see your car shaking when idle, then there is a high chance that the problem probably lies in your fuel intake system. The more you drive your vehicle, the more wear and tear your fuel intake system suffers, leading to blockages and malfunctions.

Obstructions in your fuel intake valves can lead to less fuel going to your engine, which fails to start the engine properly. This leads to vibrations in your engine, which makes your car shake even while idle.

Therefore, ask your mechanic and allow them to implement the use of an OBD2 scanner to find car engine malfunctions. This scanner will quickly pick up any obstructions in the fuel intake system.

Frequently Asked Questions (FAQs):

Here are the answers to some questions that people ask alongside why is my car shaking when idle:

Q1. How Do You Diagnose Engine Vibration?

Ans: To diagnose the reason why your engine is vibrating, you can do the following:
First, place your car in a neutral state.
Slowly start increasing the engine speed to an RPM which makes it vibrate.

Q2. What Reduces Engine Vibration?

Ans: To reduce the vibration of your engine, you can try making the coupling more flexible than before. Here, changing the spring and the damper will work wonders.

Q3. Does Changing Engine Oil Reduce Vibration?

Ans: Yes, changing the engine oil can indeed reduce your engine and car vibration. This will be most noticeable if the engine has not been changed for some time. In addition, this is more prominent in two-wheelers than in four-wheelers.

Conclusion

There are various reasons why your car shakes at idle but smooths out while driving. It can be due to iffy motor mounts, gas caps, damaged spark plugs, and battery cables. In addition, your ignition control system might be faulty as well, alongside worn-out sensors.

How does it Feel Like Riding a Bike as your Passenger?

Motorcycles first appeared in 1894, Hildebrand & Wolfmuller was the first company to produce these machines on a bigger scale. First bikes weren’t as impressive as you might think, so before you overemphasize and let yourself get carried away, I will shatter any false visions. Imagine a large bicycle with a small, cylindrical engine and fuel tank - don’t forget two simply looking handlebars! And that is it! A pretty ordinary looking machine. Thankfully the 19th and 20th century were the eras of constant advancements, motorcycles included. Ever since 2014 Honda, Yamaha and Hero MotoCorp are graded to be the largest global producers of the little, steel ponies. Some even prefer them to cars! The feelings: I want you to think about, how you feel when you get on your bike. What thoughts run through your head when the engine comes to life and purrs ever so softly? Do you feel the excitement? And then your body vibrates, in sync with the power coming from the insides on your machine. As you pick up speed, your life has a whole new rhythm and the wind in your hair reminds you, that now you and your shining pony are one. And there is nothing in this world, that could stop you! But hey, what about your riding buddy in the back? And I don’t mean your best friend with hands full of beer from the local liquor store. I’ve prepared a true treat for those, who wonder what do woman feel like when they get on a bike. Surely being the female passenger must feel different. Daniela and this really good looking guy: I knew Daniela had a very interesting summer in Brazil, somewhere in the suburbs of Rio, to be more specific – that’s why I decided to ask her about her experience with motorcycles. I guess I was a thrill seeker for a little while. I got bored of my dull life and duties of a daughter, sister, and a student. My aunt and uncle have a chain of souvenir stores in Rio de Janeiro. They promised to take me in for a few months, so I’d see more of the world or something. God knows how she ended up on the streets of Rio, with a bunch of strangers and about to participate in a street motorcycle race. Daniela couldn’t really process what was going on, somebody gave her a leather belt and she was told to let her blond curls loose from her ponytail. I chose to ride with this really a good looking guy, with raven black hair and ice blue, pinning look in his eyes. He shouted something over his shoulder and approached his bike. Maybe he offered her his name. Daniela wasn’t certain what would make her feel more comfortable and not so out of place. The bikes made their way to the race line and she hurryingly grabbed a cool looking helmet from an unattended pile of those safety features. They had no female motorcycle helmets and once I put men’s on, I could barely see a thing. So I took it off and mindlessly placed it on my hip. Her biker finally stopped playing around with his machine and gave her a funny look – ‘You know we need to sit back to back, si?’ I was excited and utterly terrified at the same time -she recalls as we sit in my living room with warm socks on our feet and large mugs of hot cocoa. And the wind outside picks up, we can hear it howl somewhere in the attic. It’s warm in the house but for some odd reason we both shiver – probably for two distant reasons. Illegal street racing: When the time came, Daniela wrapped the belt around herself and offered the side with the buckle to the handsome guy. Some viewer, a small girl with red stockings and a pair of heavy looking boots - surely no older the Daniela - ran it their direction pointing at whatever my dear friend had with her. Once Red Stockings got closer, she shouted something in Spanish. Darn, I should have paid attention in class! At that moment I had no idea what to say. Before my friend started panicking about her inability to speak Spanish, the girl pointed at the helmet and said ‘Casco, no.’ – and took it from her hands with a toothy grin. And then they unexpectedly took off. All Daniela could hear was her own screams, she shut her eyelids closed and as they picked up speed the chilly night air hit her face. I swear, all I could hear was the roaring engine and the cheering crowds. She has never ridden a motorcycle, let alone back to back in a most likely illegal street race! Daniela squeezed her hands tighter around the guy’s waist and waited for it to end. There were 5 labs in the opening race and she remained in that uncomfortable position. We got off the bikes for a ten-minute break, I was shaking like crazy and blood pulsed in my ears. But something made me go again, and again, and again. Daniela was a passenger on a street race motorcycle every week, for a few months during her time in Brazil. The Need for Speed: What attracts these people to do such crazy things? I will never know because speed makes me nervous. I enjoyed Daniela’s story and hopefully, you did too! But remember, we are only people – really fragile beings and sometimes we do before we think. So don’t go experimenting with motorcycles and speed in a street race the first time you try. If your a biker with greater experience, please remember that there is something like adrenaline addiction – and this is a dangerous thing to be hooked on. Helmets up, speedometers down and be careful! If you really want to woo your girl with the help of your steel pony take her for a ride, not a race – stargazing and dinner recommended.

How to Improve Internal Combustion Engine Efficiency

Nowadays there is a lot of concern over increasing combustion engine efficiency. There are many methods, which have been devised by engineers like turbocharging, regenerative banking, VIT and direct fuel injection, which can help improve the internal combustion engine efficiency. For example, with the help of Tribotex, you can increase the internal combustion engine efficiency. Before we delve into the ways of improving the energy efficiency of an engine, we need to know what is meant by combustion energy efficiency and how can it be calculated. The energy efficiency of the engine is simply the ratio of the fuel supplied to do the work in a specified time to the amount of work done or the output received after all the losses. When you measure the heat balance sheet of the different engines, you can easily find out the engine efficiency. Factors That Limit Internal Combustion Engine Efficiency : There are certain factors, which limit the efficiency of the combustion engine. They are Heat loss during cooling or in exhaust gases Friction loss Loss in transmissions like clutches, fluid couplings, and brakes Friction loss in tires Incomplete and imperfect combustion Loss due to the thickness of viscosity of lubricant in the engine The drag of the vehicle Imperfect valve timing Compression ratio Energy consumed by auxiliary equipment like water pumps and oil pumps So, now that you know about the ways in which the internal combustion engine efficiency can be reduced, let’s have a look at how you can improve it. Regenerative Braking : Whenever you apply the brakes of a car, you waste some fuel due to deceleration and friction, in addition to heat from your combustion engine. In order to avoid that, regenerative braking should be used. The process is similar to you controlling the speed of the vehicle while going downhill, or slowing your car first before you press the brake. You can also use electromagnetic braking, in which the motors will absorb the energy and use it for recharging your battery cells. Direct Injection : If you do not use direct injection, the fuel is mixed with the air outside, making it more prone to getting wasted. However, when you use direct injection, the fuel is mixed with the air inside the cylinder or injected directly in the cylinder, which allows better control of the fuel being used. This also makes your engine more efficient. Cylinder Deactivation : When you have an internal combustion engine with a special feature, you can deactivate some cylinders when the power requirement is less. This reduces the total volume of engine cylinders temporarily and also reduces your fuel combustion, increasing the efficiency in return. Turbochargers : Turbochargers are equipment used to increase pressure inside the fuel cylinders, and generate more air, and allowing the combustion to occur so that more power can be generated. Although this doesn’t make the engine more economical, it helps in the generation of more power with a small amount of fuel. This, in turn, helps you to downsize other costs. Variable Valve Timing : Inside the combustion cylinder, valves open and close at frequent intervals to allow air to enter the cylinders, and the combusted air to exit. Different valve timing is required to produce different results. In theory, you cannot vary the timing, because it is an automatic mechanism that depends on several other factors, and the choice has been made when the engine was designed. However, with some modern engines, the option to vary the valve timing is there. It can be changed by changing the rotations per minute or even allowing maximum power, and fuel to pass through. Twin Spark Plug : When the flame front starts from the spark plug, the plug proceeds outward and some part of the fuel remains unburnt, which is then ejected out as a waste. However, when you use a twin spark plug cylinder, the flame front also uses the remainder of the fuel, increasing the fuel efficiency of the engine in general. When it comes to building energy-efficient cars, the first step is taking care of the efficiency of the engine, along with certain other factors. For example, when you use a lubricant with less viscosity, your energy efficiency increases to some extent. At the end of the day, make sure you check the above-mentioned factors if you are planning to improve the internal combustion engine efficiency. Read More : 1.

Are You Thinking About Buying Quad Bike For Your Kid?

Every child's wish is to have one at some point in his childhood. Can you blame them? Just as you look at them, you will realize how exciting they look for us adults let alone that fun that kids imagine having on them. The million-dollar question that haunts most parents is- are they safe as they are impressive? What specifications do you need to know before getting this best birthday gift for your child? Let us give a brief overview of everything regarding these thrilling vehicles. If you are a parent that is concerned about giving your children high-performance machines, you can start with the smaller 49cc quad bike. They are safer and will ensure that your kids get a hang of riding these machines before progressing to bigger and higher displacement machines. Quad bikes for children need to be fun, exciting as well as ensure the maximum amount of security. If the quad bike is satisfying all those parameters, as parents, you need not be worried about them getting injured riding one. Here Is What You Need To Know Before Purchase: In recent years, children's quads have been increasingly successful. A 4 wheeler for 6-year-old will be one of the most memorable things from his childhood regardless of any present that you gave him. These four-wheel vehicles are the passion for motor enthusiasts and outdoor adventures, in any type of terrain. These vehicles are also very beautiful from the aesthetic point of view and we do not find any compromises in terms of design or functionality even though they are produced for children. The manufacturers of vehicles for children have immediately launched many models to amaze our children and their parents. From their earliest age, they have the opportunity to imitate the maneuvers that their father or uncle is able to do with the real quad. We need to take careful consideration of the fact that these machines are very close to being or are identical to the real quad-bikes. There are even models with internal combustion engines, but they are dedicated to older children. Nevertheless, what you are probably interested in are four-wheelers with an electric motor ranging from 6V for smaller kids to 12V models that are able to reach speeds a little higher than every 10-year-old child would give everything to have. Many models follow the lines of the already famous quad bike models. Others replicate the design of automobiles and cars, and there are even models that have designs and colors dedicated only to the girls, while still others have a futuristic look and seem to come out of one of those post-apocalyptic films. In terms of engineering, the smaller quad vehicles come with low-pressure tires, and steering the quad is enabled through manual handlebars. In engineering terms, the smaller quads are quite a marvel in terms of design and handling capabilities. Most of the vehicles on the market for children can be enjoyed and operated by one person only (they are equipped with one seat). However, there are a few optional extras and models where customers can have the extra seat option available. If we are to compare the smaller quads, which have specifically been built for children to enjoy with the quads of their adult counterparts, we find that in addition to enjoying them for adventure sports, adults often use the practical machines for farm use. If you are wondering about how efficient these quad machines are and are somehow concerned about their energy consumption, we would be happy to point out that unlike similar machines for adults, manufacturers engineer the smaller quads in a way, that they consume significantly lesser energy on account of their smaller engines (lesser cubic capacities). The Best “Toy” That Your Child Will Ever Have: Children who are new to the field of riding are usually between 4 and 7 years old, while children with more experience are usually between 8 and 12 years old. While these age groups are merely a consideration, consider your child's experience and level of maturity when driving a vehicle before committing to purchase one. Electric quads maintain a lower throttle and speed limit, with a better driving experience. It is also advisable to check the reliability of the electric brakes, the high-speed locking options, and the padded handlebar, especially for the amateurs. Many kids are more geared towards exploration and adventure than others are. Some of them are even daring enough to take these vehicles out at night to explore newer terrains, and experiences. For such adventurers, manufacturers have armed the machines with nightlights and reflectors that end up guaranteeing not only a more satisfying experience but more importantly, they ensure a far superior level of security. Other important safety features to consider are speed limiters, controlled access through a key ignition, remote control, or switches. Depending on your needs, there are specific models that allow additional add-ons such as an extra seat for the passenger or additional storage space. In the end, I know very well what you might be thinking right now. Since that there is no reason not to buy such an amazing gift for your child if you can afford it, the only worry that you might have is the overall safety of your child while on the road. However, we would like you to remember, that with such safety measures with only one click the bike can be turned off and everything that has been done to improve these machines in the present is oriented to their safety. The most important thing for a parent is to ensure the utmost security for their loved ones. With this in mind, we strongly suggest investing in added accessories and other safety add-ons like helmets, riding gloves, protection pads for the elbows and knees, and any other requirement that would be individually suited to your child. If you really want a child to feel special, a quad bike is definitely going to crown you undisputedly, as the coolest parent in the neighborhood.
