What Causes the Throttle Pedal to Vibrate?

[Flores]

The reasons for throttle pedal vibration are: 1. Engine-induced resonance transmitted through the vehicle body to the throttle pedal; 2. Prolonged driving time leading to excessive dirt accumulation in the throttle body, causing incomplete closure and resulting in high idle speed of the engine; 3. Excessive carbon deposits generated during engine operation, causing throttle vibration, especially noticeable during vehicle startup when the engine tends to vibrate more severely. Severe carbon buildup may even prevent the vehicle from starting. Solutions for throttle pedal vibration include: 1. Cleaning the vehicle's fuel system, starting with the throttle body to check for blockages and inspecting the fuel injectors for excessive carbon deposits; 2. Checking the engine mounts; 3. Regular vehicle maintenance and timely oil changes.
