What are the causes of vehicle idle vibration?
1 Answers
Vehicle idle vibration can be caused by the following reasons: 1. Spark plugs fail to fire or fire poorly due to prolonged use without replacement or installation issues. 2. Damage to the ignition coil of one cylinder, causing that cylinder to malfunction. 3. Internal short circuit in the fuel pump, leading to insufficient low-pressure fuel supply and resulting in engine vibration or stalling. 4. Air leaks in the engine intake system, causing engine vibration and triggering the engine fault light. 5. One of the engine cylinders lacks compression due to poor valve sealing or carbon deposits jamming the piston rings, leading to engine vibration.
