check engine light comes on after a few miles of driving - Visitor
My engine light comes on and my engine idles rough, but as soon as the light goes off (randomly) the engine runs fine. The gas cap light comes on my dashboard warning me the it is not secured, I twist of the cap and put it back on, sometimes this will trigger the warning to go off and everthing is fine. That would be wonderful it that was all it was. I am replacing my plugs, air filter and fuel filter to see if these contribute to the light being on. - Visitor
