Why is the engine shaking intermittently?
1 Answers
If you notice the engine shaking intermittently, it may indicate the following potential issues with the vehicle: 1. Ignition system problems: Check the working condition of spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or suboptimal spark plug firing can lead to such symptoms. 2. Severe engine carbon buildup: The most common cause of vehicle shaking is excessive dirt on the throttle body or carbon deposits in the fuel injectors. 3. Unstable fuel pressure: It is recommended to visit a 4S shop to check whether the fuel supply pressure and intake pressure sensor are functioning normally. Abnormal fuel pump pressure or incorrect readings/malfunction of the intake pressure sensor can cause body vibration.
