Why is my Car Shaking and the Check Engine Light On?
I was driving home from work the other day when my car started shaking violently. The check engine light came on, and I had no idea what to do. I pulled over to the side of the road and called a tow truck. When the mechanic looked at my car, he said that the shaking was caused by a misfire in one of the cylinders. This article will try to answer the question “Why is my car shaking and check engine light on?”
When the check engine light comes on and your car starts shaking, it means that there is something wrong with your engine. A misfire occurs when the spark plug ignites the air-fuel mixture in the cylinder. If the spark plug is not working properly, the air-fuel mixture will not ignite, and the cylinder will not fire. This can cause the engine to shake and lose power.
Misfires often occur for simple reasons. Spark plug misfires are a common problem. Typically, a faulty spark plug is to blame. Other possible causes include a bad spark plug wire, a faulty ignition coil, or a weak fuel pump. Other causes of misfires can be more serious, such as a blown head gasket or a problem with the engine’s timing. Replacing faulty parts can help resolve this.
A misfire can be a minor or major problem, depending on the cause. If your car is shaking and the check engine light is on, it is important to have it checked out by a mechanic as soon as possible.
