What Causes the Abnormal Noise When Accelerating?

[StJayce]

The causes of abnormal noise when accelerating are as follows: Abnormal noise from the fuel pump motor: When there is wear or impurities inside the fuel pump motor, abnormal noise will occur when accelerating. This issue requires replacing the fuel pump. Abnormal noise from the throttle: Modern throttles are electronic, and the motor controls the opening and closing of the throttle. When the motor gears are worn, insufficient engagement can cause abnormal noise. Excessive carbon deposits or sludge in the throttle can also lead to abnormal noise. The throttle can be cleaned, but if the motor is damaged, the throttle needs to be disassembled to replace the servo motor. If there is abnormal noise when accelerating, first check if the dashboard or workbench is loose, then inspect the transmission. Oil contamination inside the transmission can cause abnormal noise from the transmission oil pump.
