The most common cause of jerking in the car while you accelerate is the transmission. If your vehicle has a manual transmission, this jerkiness may be due to a lack of fluid or air in the lines, which can cause rough shifting and jerkiness.

If your vehicle has an automatic transmission, the jerkiness could be due to weak engine performance or low power. So if you’re experiencing jerking in the car while accelerating, it’s worth checking out these possible causes and getting that fix.

  • Clogged fuel filter 

As the fuel flows through the filter, the dirty particles in the gas go through. Still, any particles of sand, metal, etc., clog up the inside of the filter and affect a car’s performance, causing jerking while accelerating.

  • Fuel pump issues

The damage to your engine due to low or no fuel can also cause jerking in the car while accelerating. 

This is because your engine needs a good supply of fuel to run correctly, and if that’s reduced or stopped completely, things won’t work correctly, which will cause jerking in the car while accelerating. 

The most common culprit for this could be a faulty fuel pump which needs replacing.

  • Loose gas cap

The cap on your gas tank is one of the essential parts of your car, and if you find that it’s not correctly closed or can’t be fastened, this could cause jerking in the car while accelerating. 

Loosening the cap or replacing it with a new one can cure this problem once and for all.

  • The air filter has clogged.

If you have noticed increased gas mileage from replacing your old air filter with a brand new, higher quality one, you will likely need to replace your old filter again due to such leaks as oil, dust, etc. 

These particles get into the engine and affect car performance causing jerking in the car while accelerating.

  • Ignition timing is off.

The ignition timing can also cause car to jerk while accelerating, often caused by a problem with your distributor or the spark plugs. Have them checked out to get this problem fixed once and for all. 

Just as your air filter can allow dust, oil, particles, etc. to enter the gas that you’re pumping into your engine, so too can the throttle body, which will cause jerking in the car while accelerating.

Do Defective Carburetors Causes Jerking In The Car?

Carburetors are used with internal combustion engines to mix air and fuel. The carburetor controls the amount of fuel injected into the combustion chamber, so its function is central to how an engine operates. 

A defective carburetor can lead to jerky movement when driving or acceleration, sometimes accompanied by a clunking noise. 

The fuel tank and air filter must be cleaned and checked regularly. The internal combustion engine can also cause jerking during acceleration if poorly tuned. 

Ensure your engine is tuned regularly. Carburettors sometimes get clogged with dirt and rust, leading to poor gas flow or poor ventilation of the carburetor.

This will cause a problem with how your car performs since the mixture of air and gas will not be able to be drawn through. 

If your carburettor is blocked, you may experience jerking on acceleration or even no acceleration at all.

Symptoms Of Dirty Fuel Injectors

Clean fuel injectors are vital to the longevity of your engine, but with all that you have going on, they may be easy to overlook. But if you think your vehicle is misfiring, lagging, or stalling, and then dying even when shut off, then it is possible that they need to be cleaned.

To prevent getting it clogged with dirt, you can watch out for a few symptoms such as:

  1. Dizziness: Maintaining a proper air and fuel mixture; if your car is not running, the engine may act up, and stalling can occur.
  1. Unusual sounds: If your car makes unusual sounds, it may also be a sign that the fuel injectors require cleaning.
  1. Engine misfire: It can cause your engine to stall out or not run at all while driving or while idling.

Fuel injectors are responsible for delivering the proper fuel to your engine’s cylinders at a specific time. If you’ve experienced any of these symptoms recently, the most common cause is dirt in your fuel injector lines.

How To Fix The Issue Of Jerking In A Car?

There is nothing worse than when your car begins to jerk around corners. It feels like the wheels have left the ground, and it’s an intense, uncontrollable shake. The whole steering wheel might even be shaking, making driving a scary experience that is unsafe for passengers and other drivers on the road.  

DIY: A Fix for Car Engine Jerking

If you’re having trouble with the jerking of your car, the first thing to do is check your transmission fluid. Then, if it’s low, make a trip to your local mechanic and have them replace the fluid and filter so that you’re back on the road in no time.

If this does not solve your problem, there may be a problem with one of the tires or rims. 

Make sure that they are correctly inflated and in good condition before making another visit to have them replaced if needed. The last option would be an issue with something inside the engine compartment. 

But if you cannot find the problem in your car, it would be better to take your vehicle to a good mechanic for a proper diagnosis to fix it as soon as possible.
