What Causes the Buzzing Sound When Pressing the Accelerator?

[OwenDella]

Reasons for the buzzing sound when pressing the accelerator: 1. Abnormal noise from the fuel pump motor: When the fuel pump motor is worn or contains impurities, it may produce abnormal noise upon acceleration, requiring replacement of the fuel pump; 2. Throttle body noise: Modern throttle bodies are electronically controlled, and the motor that controls the valve opening and closing may produce noise if its gears are worn and do not engage properly; 3. Poor lubrication of the accelerator pedal bearing, which can be resolved by applying grease to the bearing; 4. Damaged clutch release bearing, causing incomplete separation of the clutch plate and resulting in noise, necessitating removal of the clutch and replacement of the release bearing.
