i just recently bought a '91 mustang gt cobra,auto, the check engine light currently went on , so i pulled over and restarted the car , and it went off, i've been driving the car for a week and the light didn't come on again. and just today the check engine light came back on........ any ideas ????? car drives smoothly , starts fine, never stalls.
