Causes of Car Vibrations When Idle with Check Engine Light
There are a number of potential causes for car vibrations when idling with the check engine light on. Some of the most common causes include:
* **Spark plug problems.** Spark plugs are responsible for igniting the air-fuel mixture in your engine. If one or more of your spark plugs is faulty, it can cause your engine to misfire, which can lead to vibrations.
* **Fuel injector problems.** Fuel injectors are responsible for delivering fuel to your engine. If one or more of your fuel injectors is clogged or faulty, it can cause your engine to run lean or rich, which can also lead to vibrations.
* **Intake manifold problems.** The intake manifold is responsible for delivering air to your engine. If the intake manifold is cracked or damaged, it can allow air to leak into your engine, which can cause vibrations.
* **Exhaust manifold problems.** The exhaust manifold is responsible for removing exhaust gases from your engine. If the exhaust manifold is cracked or damaged, it can allow exhaust gases to leak into your engine, which can also cause vibrations.
* **Engine mounts.** Engine mounts are responsible for holding your engine in place. If one or more of your engine mounts is loose or damaged, it can allow your engine to move around, which can cause vibrations.
