A loose or faulty gas cap. This is one of the most common reasons why the check engine light comes on. The gas cap helps to keep the fuel vapors from escaping the fuel tank, and if it’s loose or faulty, it can cause the check engine light to turn on.
A misfiring engine. This means that one or more of the cylinders in your engine is not firing properly. This can be caused a number of things, such as a bad spark plug, a faulty ignition coil, or a problem with the fuel system.
