What Causes Abnormal Noise When Pressing the Accelerator?

[DelPaisley]

Causes and solutions for abnormal noise when pressing the accelerator are as follows: 1. Abnormal noise from fuel pump motor: When the fuel pump motor is internally worn or contains impurities, it will produce abnormal noise when the accelerator is pressed. This issue requires replacing the fuel pump. 2. Abnormal noise from throttle body: Excessive carbon deposits or sludge in the throttle body can also cause abnormal noise. Cleaning the throttle body can resolve this. 3. Poor lubrication of accelerator pedal bearings causing noise: You can apply grease to the bearings for lubrication. 4. Damaged clutch release bearing: This can cause incomplete separation of the clutch disc, resulting in abnormal noise. The solution is to remove the clutch and replace the release bearing.
