the check engine light comes on quite often. but i held the dash button and turned the car on, (so it would give me the code to whats wrong) and it says "no faults" each time. then i tighten my gas cap and it goes away soon after. and no, i never run a/c in my car. and it runs fine, the only times i have problems is when im stopped.
