## Engine Light Came On and Car Is Shaking: What Could Be Wrong?
When you see the dreaded check engine light come on, it’s natural to panic. But don’t worry, not all check engine light problems are major. However, if your car is also shaking, it could be a sign of a more serious problem.
**Here are a few of the most common causes of a check engine light and car shaking:**
* **Misfiring engine:** A misfiring engine occurs when one or more of the cylinders in your engine is not firing properly. This can cause your car to shake and vibrate, and it can also lead to decreased fuel economy and performance.
* **Vacuum leak:** A vacuum leak occurs when there is a hole or crack in one of the vacuum hoses in your engine. This can cause your car to run lean, which can lead to shaking and stalling.
* **Faulty spark plugs or wires:** Faulty spark plugs or wires can also cause a misfiring engine. This can lead to shaking and vibration, as well as decreased fuel economy and performance.
* **Clogged fuel filter:** A clogged fuel filter can restrict the flow of fuel to your engine. This can cause your car to run lean, which can lead to shaking and stalling.
* **Dirty throttle body:** A dirty throttle body can also cause a misfiring engine. This can lead to shaking and vibration, as well as decreased fuel economy and performance.
**If you see the check engine light come on and your car is shaking, it’s important to take your car to a mechanic as soon as possible. The mechanic will be able to diagnose the problem and recommend the best course of action.**
