This may be the abnormal sound of the pump motor.

Abnormal sound of gasoline pump motor: When there is wear or impurity inside the gasoline pump motor, stepping on the accelerator will make abnormal sound, so it is necessary to replace the gasoline pump. Abnormal sound of throttle valve: now electronic throttle valve is used, and the opening and closing of valve are controlled by motor. When the gears of the motor are worn, they are not fully meshed, resulting in abnormal sound. Poor lubrication of the accelerator pedal bearing will produce abnormal noise, so you can grease the bearing. The clutch release bearing is damaged, resulting in abnormal sound due to incomplete separation of clutch plates. Remove the clutch and replace the release bearing.
