What Causes Abnormal Noise from the Accelerator Pedal?

[VanLane]

Abnormal noise from the car's accelerator pedal is mainly caused by the following reasons: 1. Carbon buildup in the throttle causing sticking—clean the throttle. 2. Wear on the accelerator pedal pivot pin—applying grease can solve the issue; if not, replace it. 3. Poor installation of the accelerator cable. For electronic throttle systems, check the accelerator pedal mechanism and the accelerator pedal sensor. Precautions for operating the accelerator pedal: 1. Avoid using excessive throttle when starting an unloaded vehicle; a light throttle is recommended. For loaded starts, a moderate throttle is advisable. 2. Set the throttle to an appropriate position during startup to reduce wear on mechanical parts. 3. Avoid sudden acceleration while driving. To increase engine speed, gradually apply more throttle to ensure a smooth rise in engine RPM.
