What causes the car to jerk when accelerating?

[Corbin]

Car jerking during acceleration can be caused by: 1. Poor coordination between the throttle and clutch during gear shifting; 2. Excessive engine carbon buildup; 3. Incomplete fuel combustion affecting power output; 4. Insufficient fuel pump pressure; 5. Clogged or leaking fuel filter. The throttle, also known as the accelerator pedal, primarily controls the opening of the engine's throttle valve to regulate power output. With the continuous development of automotive electronic technology, electronic throttles are becoming increasingly widespread. When a driver presses the electronic accelerator pedal, it essentially sends a throttle position sensor signal to the engine ECU.
