check eng light

I've got a 93 3.4l camaro. The check engine light will come on I guess when it feels like it, and go off whenever. It has never stayed on very long, but it gets annoying to see it there.

anyone got a suggestion.

Sounds like EGR or IAC problem..Does it affect the engines performance? Run the codes and that'l tell you.. If you dont know how, ask..
