Not a lot to go on. If its just staying lit, then your probably fine. Make sure your gas cap is tight. If it was flashing at you then that means multiple misfires. Could be from the plugs and wires, but you would feel it. Otherwise, make sure you dont take it to a dealer. They will screw you in the back door without vaseline. Autozone, advance auto, etc do the scan for free. Also, many members have Autotap or LS1M which can also scan the codes. Good luck.
