Old spark plugs or worn ignition coils can cause misfires, which can result in jerking during acceleration.
2. Dirty Throttle Body
A throttle body that is clogged with carbon deposits can prevent the engine from getting the proper amount of air, causing jerking.
3. Faulty Mass Airflow Sensor (MAF)
The MAF sensor measures the amount of air flowing into the engine, and if it is faulty, it can send incorrect information to the engine computer, which can result in jerking.
4. Failing Transmission
Transmission issues, such as low transmission fluid, worn clutches or torque converter problems can cause jerking as the transmission shifts.
5. Clogged Fuel Injectors
Clogged fuel injectors can prevent the engine from receiving enough fuel, causing it to jerk when accelerating.
6. Vacuum Leak
A vacuum leak in the engine can disrupt the proper balance of air-fuel mixture, resulting in engine jerks.
7. Worn Engine Mounts
Worn or broken engine mounts can cause jerking as the engine vibrates excessively during acceleration.
8. Damaged CV Joint
Damaged constant velocity (CV) joints, commonly found in front-wheel drive vehicles, can cause jerking while accelerating due to uneven power transfer.
9. Faulty Engine Sensors
Other sensors, such as the oxygen sensor or crankshaft position sensor, can also cause jerking if they are faulty or provide incorrect data.
10. Software Issues
In rare cases, software-related issues in the engine control unit (ECU) can cause jerking, requiring software updates or reprogramming.
