What Causes Abnormal Noise During Rapid Acceleration of a Car?

[SanOmar]

Here are the reasons and solutions for abnormal noise when stepping on the accelerator: 1. Abnormal noise from the fuel pump motor. When the fuel pump motor is worn or contains impurities, it can produce abnormal noise as we step on the accelerator. Solution: Replace the fuel pump. 2. Throttle body noise. Modern throttle bodies are electronic, and the motor controls the opening and closing of the throttle. When the motor gears are worn, improper meshing can cause abnormal noise. Excessive carbon deposits or sludge in the throttle body can also lead to noise. Solution: Clean the throttle body; if the motor is damaged, disassemble the throttle body and replace the servo motor. 3. Poor lubrication of the accelerator pedal bearing causing noise. Solution: Apply grease to the bearing for lubrication. 4. Damaged clutch release bearing, leading to incomplete clutch disc separation and abnormal noise. Solution: Remove the clutch and replace the release bearing.
