7 Reasons Why Car Jerks When Accelerating


When a car jerks as you start it, there is no doubt that there is something wrong with it. Sometimes, it would get passed through the acceleration phase but it could continue while your driving. It is safe to say that your car is having some problems and I am here to help you identify it.

And today, you will learn more about it as I will enumerate each one for you. Not only will you learn about why your car is acting up, but you will also learn how to solve it.

Check Engine

One of the most common reasons of your car jerking as you accelerate is a possible blockage in its engine. If you don’t remove that blockage, your car will continue to jerk because gasses are not coming out of it when they are supposed to. You will know that this is the case when the “Check Engine” light in your car is on.

Don’t ignore that light, especially when it is blinking. Aside from jerking as you accelerate, you will notice that your gas level could easily go low. At this point, I will suggest to call a professional to remove the blockage. If you don’t act on it quickly, you will gas and that is just wasting your money.

Check the fuel filter for dirt because that might be the reason your car is acting up. If you haven’t clean that area of your car, then there is a huge possibility that dirt has already built up in there. All you need to do it wipe those off and check if your car would do jerk again as you accelerate.



This is one of the most neglected parts of the car, the injectors. You will know this is the case when your car completely loses its power.

It is also a symptom when your car not only jerks but if you see your engine firing something out there while you are driving, then your car’s injectors are definitely messed up. The truth is that it’s not that serious to fix it. You don’t even need to hire someone.

You will just need to clean that area using a special kit solely for injectors. They are not expensive and you could easily buy them in your local hardware store or even online. I would also suggest that you do it on a regular basis so it doesn’t end up clogging your engine.

Moist Distributor Cap

Moist Distributor Cap

This is one of the major reasons why a car jerks while accelerating and sometimes, the weather is to blame. This usually occurs during the winter when you park your car outside and it is just extremely cold.

What happens is that the distributor cap could accumulate moist, which then results in the engine to be an imbalance. If the engine is not even, you can expect it to misfire as you accelerate your car.

The solution here is actually prevention. Don’t park it in a cold driveway instead choose a warmer environment.

Motor Winding

Motor Winding

If you stressed out the engine, you can expect that it would go on a motor winding mode on its own. Soon as your car engine starts to wind, the jerking on your car could be felt. If the car winds only once, you can already expect your car to no longer start.

To check the motor of your car if it is winding or not and the number of times it did, you will need an Ohm meter.

Wrong Alignment

Wrong Alignment

Sometimes the engine nor the motor of the car is not the problem here, it could be that your car is having a bad reaction to pulling. It is often confused by car owners as jerking but really, it is just your car moving really slow.

To solve this, you will have to c heck you r tires and make sure that pressure in them are done right. Make sure that you have a handy tire inflator product with you at all times in case tire pressure is low.

There is a chance that it was messed up when your car suffered from some traumatic experiences. You will need to align your car’s tire again the right way to fix this.

Spark Plug Error

Spark Plug Error

The cables of your car could be sensitive that it won’t surprise me if that is the reason why your car jerks. This often involves the spark plug and when this is the case, you will need to change that plug immediately.

In order to prevent this from happening, you have to make sure that the spark plug is always neat. Whenever they get dirty, you can experience not only the jerking of your car during acceleration but there could also be other serious problems


These things written here are most likely what is wrong with your car and here are your best bets in fixing it. To put it in a nutshell, most of the time, a dirty engine and other car parts could be the main reason why your car jerks upon starting.

Always clean your car on a regular basis and do at least an annual overall checkup of your car to know its current condition. Make sure that it is also parked in a place with just the right temperature, which is not too cold and not too hot. A little warm would do because it would prevent it from developing moist inside the distributor cap.

If your car is not too dirty, you can opt for a waterless car wash so that you can also save on water.​

This is just a way of properly maintaining your car so you don’t have to encounter hassles such as this one. It is also good if you are handy enough in knowing some of the basic things in troubleshooting car problems.

However, if you don’t really know how to fix it like unwinding the motor and realigning your tires, don’t hesitate to call a mechanic.
