- Engine mounts: The engine mounts are responsible for holding the engine in place and preventing it from vibrating excessively. If the engine mounts are worn or damaged, they can cause the engine to vibrate at a light.
- Spark plugs: If your spark plugs are not firing properly, it can cause the engine to vibrate at a light. This is because the combustion process in the engine is not happening smoothly, which can cause the engine to shake.
- Fuel injectors: If your fuel injectors are not working properly, it can cause the engine to vibrate at a light. This is because the fuel is not being injected into the engine properly, which can cause the engine to run lean or rich, which can lead to vibration.
- Vacuum leaks: If there is a vacuum leak in your engine, it can cause the engine to vibrate at a light. This is because the vacuum leak is allowing air to enter the engine, which can cause the engine to run lean, which can lead to vibration.
- Transmission issues: If your transmission is not working properly, it can cause the engine to vibrate at a light. This is because the transmission is not properly transmitting power to the wheels, which can cause the engine to lug or stall, which can lead to vibration.
If your engine is vibrating at a light, it's important to have it diagnosed by a qualified mechanic as soon as possible. This will help to identify the cause of the vibration and ensure that it is repaired correctly.
