What Causes Throttle Vibration?
1 Answers
Throttle vibration causes: 1. Engine vibration transmitted to the throttle pedal. If you feel the throttle pedal vibrating when pressing it, it is mostly caused by engine resonance transmitted through the vehicle body to the throttle pedal, making your foot feel the vibration when placed on the pedal; 2. Damaged engine mount dampers. When the engine mount dampers leak oil or age and break, their vibration-damping effect significantly decreases, inevitably causing throttle pedal vibration; 3. Clutch slippage. In manual and dual-clutch transmission models, the power transfer and disconnection from the engine to the transmission are completed by friction plate clutches. If the clutch plates are severely worn and slipping or the damping springs are broken, it will cause throttle pedal vibration.
