What Causes the Abnormal Noise Inside the Car When Accelerating?

[JaylaMarie]

It is abnormal for a car to make strange noises when accelerating. The reasons for abnormal noise when stepping on the accelerator are as follows: Fuel pump motor noise: When the fuel pump motor is internally worn or contaminated with impurities, it will produce abnormal noises as the driver presses the accelerator. In such cases, the fuel pump needs to be replaced. Throttle body noise: Modern throttle bodies are electronic. The motor controls the opening and closing of the throttle valve. When the motor gears are worn, inadequate meshing can cause abnormal noises. Excessive carbon deposits or sludge in the throttle body can also lead to noise. The throttle body can be cleaned, but if the motor is damaged, the throttle body must be disassembled to replace the servo motor. Poor lubrication of the accelerator pedal bearing: Poor bearing lubrication can cause abnormal noises. You can apply grease to the bearing for lubrication.
