There are 15 known causes for the jerking motion that occurs as you speed in your vehicle.

Car jerking is still a problem despite the fact that several improvements have been made to automobiles over the past few decades and a number of concerns have been resolved.

When you speed, your vehicle may have jerks, and if you do not solve these issues as soon as they arise, the majority of them will become more severe over time.

The following is a list of some of the most typical reasons why your car jerks when you accelerate, as well as answers to some of the questions that have been bothering you the most.

The following are some potential causes of the jerking motion that your car makes while you accelerate or decelerate:

The ignition electrode

Sparks are produced by spark plugs, which then ignite the gasoline cylinders. Because the wires in your vehicle are delicate, the engine will not operate correctly if the spark plugs are corroded, unclean, or otherwise compromised in any way. Spark plugs need to be replaced if the vehicle is jerking and there are other problems occurring when you are driving it.

In the event that the spark plugs have become worn, you will need to replace them as soon as possible. If they are unclean, you can clean them, and your vehicle will look as good as new when you do so.

The injector

The fuel injector is one of those things that people don’t pay much attention to, but if your car jerks and your engine misfires, it could be because of a problem with the fuel injector.


Because the apertures in this portion are what allow fuel to enter your engine, the efficiency of your machine will suffer if carbon deposits clog the openings in this part.

In order to resolve this issue, you will need to use a specialised kit to clean the fuel injector in your vehicle. You can place your order for it either online or by going to a local car parts store. After being cleaned, the injectors should begin functioning normally once more.

If you clean the injectors on a regular basis, you can stop this problem from occurring again.

The catalytic converter

The catalytic converter, an essential component of the exhaust system, is responsible for converting toxic exhaust gases into less damaging byproducts that are then expelled from the vehicle during the combustion process.

If gasoline and air are not properly separated in the engine, the acceleration of your vehicle will be jerky if they are mixed together.

A clogged catalytic converter is the second potential source of jerks that can be experienced by a vehicle. As soon as it becomes clogged, the exhaust will not be able to flow out, which will result in a reduction in the performance of the engine. First, you’ll be able to tell if your catalytic converter is clogged because your car will smell like rotten eggs, and then you’ll notice that your fuel efficiency is suffering as a result.

The intake of air is restricted.

While you are travelling at high speeds, the engine in your vehicle will draw in significant quantities of air in order to fuel the combustion process. Any disruption to the passage of air will result in acceleration problems, including jerking.

This disruption in the flow of air is typically the result of a significantly filthy air filter, but it is also possible for it to be the result of a damaged intake duct.

A sensor that measures airflow that is faulty.

These days, moving elements of cars are measured and controlled by sensors. In the event that the sensors fail, the components of the engine will receive inaccurate information, which will cause them to become unresponsive. Thus, the warning light for the engine should come on if this is the situation.

There is an issue with the alignment.

When neither the engine nor the rotor can be identified as the source of the problem, the issue is likely one of alignment. If you feel as though the automobile is jerking, the problem is most likely caused by the sluggish pace at which it is travelling.

The tyres should be the first thing you look at. Inspect your tyres for low pressure and inflate them if they are low if they are. You can also install brand-new tyres in place of damaged ones.

If the other components of the car that the tyre attaches to are severely out of alignment, your vehicle will not function correctly.

The ignition system

When decelerating, it is possible to detect anomalies even if you are not necessarily moving at a high rate of speed.

During that precise instant, the spark is extinguished, which results in incomplete combustion and, as a consequence, a severe engine lope.

This issue could be brought on by problems with the coil or the coil pack, worn spark plugs, or corroded plug wires.

Condensation on the inside of the distributor cap

When the situation calls for it, the engine distributor is the component that is responsible for sending sparks to the spark plug wires. If the cap seal is broken or otherwise compromised in any way, then water can get into the engine.

If you park your car outside during the winter, you will put yourself at a greater risk of encountering this issue. Because to the accumulation of moisture under the distributor cap, the engine will become out of balance, which will lead to a misfire.

Parking your vehicle in a warm location rather than an icy one is preferable, and you should avoid letting persistent heavy rain fall on it as much as possible.

Air in the ABS system.

ABS modules are standard equipment in current automobiles. In the event of an emergency, these modules are activated to adjust the level of brake pressure in order to prevent the vehicle from sliding. There cannot be any air in the brake lines for the anti-lock braking system (ABS) to function properly.

If The Mechanic worked on your brakes and your vehicle begins to shudder when you speed, it is possible that some air is still trapped inside of them.

Warping of the rotors is one of the most typical types of difficulties.

Brake pads and rotors, like all other elements of a vehicle, eventually wear out and need to be replaced in order to maintain adequate stopping power.

Because of their advanced age, the brake rotors on your vehicle will eventually overheat, leading to thermal shock. This will result in your vehicle jerking violently whenever you hit the throttle pedal.

There is a lack of transmission fluid.

To ensure that the torque converter in automatic transmissions functions correctly, it is necessary to ensure that there is a sufficient supply of this fluid. Delays in shifting can occur for a number of reasons, including insufficient transmission fluid or fluid that has gone bad. If you ignore it for a long time without taking action, it could end up causing irreparable harm to your vehicle.

Problems with the vacuum system’s leaks

If unmeasured air gets into your engine intake, you will almost certainly experience a vacuum leak. This is a highly likely occurrence. This problem most frequently manifests itself at the ducting/gaskets and hoses.

IAC valve malfunctioning

If the air conditioning compressor places a large demand on the vehicle’s engine, a malfunctioning air idle control valve could cause the engine to jerk or even stall.

Cable for the throttle old and tired

If your vehicle has a throttle plate that is driven by a cable, then it is possible that the cable has become worn out, which is causing your vehicle to jerk for no apparent reason.

Damage to the wiring on the clock springs

If your car still shudders when you accelerate when the cruise control is on, it’s possible that the clock spring is broken.

You can determine whether or not your vehicle has a clock spring by locating an electric pigtail that is attached to the steering wheel. The pigtail will serve as the controller for any accessories that have rotating parts on the steering wheel.
