There is a squeak when stepping on the gas pedal.

Causes and solutions of abnormal sound when stepping on the accelerator;

1. Abnormal noise of gasoline pump motor. When the gasoline pump motor is worn or has impurities, stepping on the accelerator will make an abnormal sound. This problem requires replacing the gasoline pump.

2. Abnormal throttle sound. The current throttle valves are all electronic, so the motor controls the opening and closing of the valve. When the motor gear is worn, it is not fully meshed, resulting in abnormal sound. When the throttle deposits too much sludge, it will also cause abnormal noise of the throttle. The throttle can be cleaned. If the motor is damaged, it is necessary to remove the throttle and replace the servo motor. The valve will also wear. Wear to a certain extent, the gap will be too large, and the air will hiss when passing through the valve.

3. Abnormal noise caused by poor lubrication of accelerator pedal bearing. You can lubricate the bearings yourself.

4. 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.

5. The air inlet is perforated and leaks. Most of the intake pipes of vehicles are made of engineering plastics, which will leak when aging and have abnormal sound when accelerating. You should go to the store or repair shop to replace and repair the intake pipe.
