What are the reasons for severe engine vibration?
2 Answers
Reasons for severe engine vibration: 1. Severe carbon deposits in the engine, causing irregular idle vibration. This type of idle vibration may persist for several days or improve temporarily, indicating potential carbon buildup issues; 2. Problems with the ignition system. If the issue is caused by wiring, it can be repaired manually. After acceleration, the vehicle may gradually experience unstable idle speed. It's important to note that after smooth driving, engine idle vibration does not occur. In such cases, the issue is likely caused by unstable oil pressure, and prompt repair is recommended.
Last time my car's engine was shaking badly, it was really scary. Common issues include aging spark plugs or carbon buildup causing uneven ignition and unstable cylinder operation. Fuel system problems are also frequent; clogged fuel injectors lead to uneven fuel spray and inconsistent combustion, resulting in significant vibration. Unstable idling might be due to a dirty air filter or a clogged throttle body. A broken engine mount is even worse, making the whole car shake. It's recommended to first check the condition of the spark plugs—replace them if they're blackened. Regularly clean the fuel system and throttle body to prevent carbon buildup. Safety first—don't push through it. Get a comprehensive diagnosis from a reliable repair shop as soon as possible. Small fixes can save you from big troubles.
