Sometimes we even overlook the fact that our car jerks abnormally. They often ignore this incident and do not know that their car is in danger. The reason is that the car driver does not fully understand what a jerky car incident is. Therefore, you can rely on some of the following phenomena to recognize a car jerking problem.

When the car jerks, you will feel that the vehicle does not have the necessary power to move forward. Even if you press down on the accelerator, your car will suddenly stop and suddenly rush forward.

This process will repeat more when the problem is not fixed in time. Another situation is when you try to accelerate the car, but the jerking will prevent you from going faster and maintaining the speed.

10 Reasons Why Your Car Jerks While Driving

Most people do not fully understand their car, so they cannot distinguish the causes of the car jerking. You can refer to the 10 reasons below to know the current condition of your car.

Dirty Fuel Injectors

Dirty Fuel Injectors
Dirty Fuel Injectors are one of the most common reasons for sudden car jerks. Specifically, it affects the accelerator pedal, making the part unable to work properly.

When the fuel injectors are dirty, your car will suddenly lose power while trying to accelerate or maintain the right speed. This is the result of an engine that burns out wrongly, providing the wrong fuel rating.


Blockages are the next cause of your car jerking. Because it prevents your car from getting the fuel it needs to accelerate. Fuel mixes with air to create an injection spark that powers your engine. If anything interferes with fuel transmission, it will have negative consequences, such as sudden acceleration of the vehicle.

Worn Out Spark Plugs

Worn Out Spark Plugs
Worn Out Spark Plugs are one of the causes of car jerking. Your spark plugs may be corroded and may not ignite the fuel in the pistons fast enough. It is this limitation that will make your car unable to accelerate as desired.

However, because buying spark plugs is not too expensive, you can replace them immediately to improve the car’s performance.

Dirty Air Filters

The air filter is one of the important details in removing pollutants from your engine. However, over time, these pollutants can build up and make your vehicle unstoppable.

Because the substances will reduce the air filter’s ability to filter the air, your car is not guaranteed good quality. To fix this situation, you just need to remove and clean the air filter and reuse it.

Damaged Cylinders

Damaged engine cylinders can affect the engine’s ability to operate, leading to loss of engine control. To overcome this situation, you need the help of car repair technicians. They will replace it if needed, ensuring your car is not jerked.

Blocked Catalytic Converters

Blocked Catalytic Converters could be the next cause of your car’s jerking. When the air-fuel mixture passes through the catalytic converter too large, a blockage can result.

Therefore, when the driver presses the accelerator, a sudden jerk will occur, which is dangerous for both people and vehicles. To fix this problem, you can either replace the catalytic converter or contact a service center.

Damaged Gas Lines

Damaged Gas Lines are the next typical cause you need to be concerned about. All gases flowing in the engine must pass through the airlines. However, when the throttle part has a problem, your car can lose pressure and jerk forward.

In some cases, your engine can catch on fire if the fuel line is constantly blocked. Therefore, you should carefully check the fuel line to make sure it does not have any faults.

In addition, there are 3 other reasons that you also need to pay attention to when having a car jerking problem:
