The CHECK ENGINE light on my dash doesn't stay on anymore. This light has been on since I bought the car in 2003. When I start the car I see the light come on with the other dash lights but it doesn't stay on like before. It started when I disconnected the battery to replace my broken turn signal stalk and when I connected the battery again it was gone. Normally after a few days of driving around it will come back on. I have been driving around for 2 weeks and it still won't come back on. Please help!
