Is Engine Shaking Normal?

[DeJasper]

Engine shaking is not normal. The causes of engine shaking are: 1. Severe carbon buildup inside the engine; 2. Aging of engine mounts; 3. Malfunction in the ignition system; 4. Fault caused by unstable oil pressure. The solutions for engine shaking are: 1. Clean the carbon deposits from the intake manifold and throttle body; 2. Inspect the engine mounts and replace them promptly if necessary; 3. Use a diagnostic tool to read the fault codes to determine which cylinder has issues, then replace the spark plugs, high-voltage wires, or ignition coils accordingly; 4. Measure whether the fuel pressure is normal and clean the fuel injectors.
