What Causes Severe Engine Vibration?
2 Answers
Generally, there are four main reasons that cause engine vibration: 1. Ignition system malfunction. Solution: Check if the spark plugs have excessive carbon buildup and clean or replace them immediately. 2. Engine mount aging or loosening. Solution: Replace the engine mounts. 3. Carbon deposit issues. Solution: It is recommended to have the engine cleaned at a 4S shop. 4. Poor fuel quality. Solution: Clean the car's throttle promptly. If the issue persists, take it to a 4S shop for repair. Always refuel at reputable gas stations, use the fuel grade specified by the manufacturer, and perform regular maintenance.
There are quite a few reasons for severe engine shaking. The most common issue is with the ignition system, such as worn-out spark plugs or faulty ignition coils, which cause the cylinders to malfunction, making the entire engine shake like riding a rocking horse. Fuel system problems, like clogged fuel injectors or a weak fuel pump, can also lead to insufficient fuel supply and shaking. Air intake system leaks or faulty mass airflow sensors can cause uneven combustion. If the engine mounts are loose or broken, the engine won't be secured properly, leading to severe vibrations. I remember one time my car was shaking badly, and it turned out to be excessive carbon buildup affecting cylinder compression—cleaning it solved the problem. Regular maintenance like timely oil changes and air filter replacements can help reduce such issues. Don't wait until the shaking gets worse to address it, as small problems can turn into costly major repairs. If your car shakes severely while driving, start by checking basic points like the ignition and fuel systems, and it's best to use a diagnostic tool to read fault codes and pinpoint the cause.
