My 95 2.2 is throwing a code 28 - Quad Driver C fault, subsequently it's throwing a code 32 EGR valve malfunction. If I view the live data while the car is running, quad drivers A, B, and D are all good. But it says driver C is bad. When the check engine light comes on, the EGR opens to 100% which leads me to believe that it's not actually a problem with the EGR, but the Quad driver is causing the problem. My first question is: what the hell is a quad driver? Second, any ideas on how to fix this problem? Thanks.
is your shift light working?
