What Causes the Jerking When Releasing the Accelerator Pedal?

[LeManuel]

The reasons for jerking when releasing the accelerator pedal are: 1. Excessive carbon buildup in the throttle body, fuel injectors, and intake passages; 2. Poor fuel quality leading to incomplete combustion; 3. Faulty spark plugs or ignition coils causing cylinder misfire; 4. Mismatch between engine torque and transmission oil pressure. Solutions for jerking when releasing the accelerator pedal include: 1. Cleaning carbon deposits from the throttle body, fuel injectors, and intake passages; 2. Replacing with qualified fuel; 3. Replacing spark plugs and ignition coils; 4. Changing transmission fluid. The function of the accelerator pedal is: By controlling the pedal pressure, it regulates the throttle opening, controls air intake, while the computer manages fuel quantity, thereby controlling engine speed.
