EGR
Can a bad egr valve cause a rich condition, like black smoke out of exhaust and fuel fouled plugs after just a few minutes of idling? I already checked for a bad AFPR, CTS etc... This is on my 1990 GTA, 5.7,tpi,LT headers with true duals and no cat. Since I have no AIR pump or any emission stuff, cant I just put a block off plate on it? Car already has new plugs, cap,rotor,dizzy,plug wires, stock chip and injectors. I had 24# svo's in it but took them out to rule them out as possible cause.
