Car Shaking and Check Engine Light On
If your car is shaking and the check engine light is on, it could be a sign of a serious problem. There are a few different things that could cause this, so it’s important to take your car to a mechanic to have it diagnosed.
Possible Causes
- Misfiring engine: This can be caused by a variety of problems, such as spark plug problems, fuel injector problems, or ignition coil problems.
- Vacuum leak: A vacuum leak can cause the engine to run lean, which can lead to shaking and misfiring.
- Loose or damaged motor mounts: Motor mounts hold the engine in place. If they become loose or damaged, the engine can shake when it’s running.
- Driveline problems: Driveline problems, such as a worn out CV joint or a faulty driveshaft, can also cause the car to shake.
What to Do
- Take your car to a mechanic as soon as possible to have it diagnosed.
- In the meantime, avoid driving your car if possible, as it could cause further damage.
- If you must drive your car, be sure to drive carefully and avoid sudden stops and starts.
Cost of Repairs
The cost of repairs will vary depending on the cause of the problem. Here is a general idea of what to expect:
- Misfiring engine: $500-$2,000
- Vacuum leak: $100-$500
- Loose or damaged motor mounts: $300-$1,000
- Driveline problems: $500-$2,000
Conclusion
If your car is shaking and the check engine light is on, it’s important to take it to a mechanic as soon as possible to have it diagnosed. The problem could be serious, and it could be dangerous to continue driving your car if it’s not repaired.
