Hi all, I'm new to the forum.
My Equus 3100 OBD-II scan tool cannot pull codes for my '95 Cavalier 2.2L. I know this was the "transition" year - having the newer OBD-II style 16-pin connector, yet is not OBD-II compliant. How (and with what) do i retrieve the trouble codes????????
I am getting only intermittent "Check Engine" lights once car is warmed - and always only for a few moments at a time. Problem is the damn thing is running very rich - fouling the plugs with fuffy carbon after a few hours of driving, to the point where it hesitating badly under load, and of course my fuel economy is gone to hell.
It has new plugs (NGK Platinum TR55GP) and plug wires, new O2 sensor, new air filter. Any help would be appreciated.
