my son has a 92 grand am gt and we just did some work to it, it also had the code for the quad driver module. You can have this part tested at a mechanic. If you dont know its the main board under the caps where the spark plug wires go to. Our sons car also had the oil and check engine lights come on. Oh btw our sons QDM was bad, it was only sparking on 4 of the 6 posts, we replaced it, $150 and his car starts right up.
