Mine is a non-Turbo and it is running rich and the exhaust is slightly smokey and it stalled at times when cold or poor take off.
Brief history, previously stated parts replaced and it ran cruddy. One website said leaking injectors. Did the o-rings. Ran the vehicle and disconnected the O2 sensor while runnning the car and their was no change in idle AT ALL, is that correct? Left that unplugged and went to the AMM and unplugged it, a flutter then idle, replugged it and the idle jumped up to 1500+. Shut it off and it idled normal.
I read the FAQ's and everything tells me the ECU but.... there is a grounding issue that has me stumbled. The P(ink) and B(lack) colored wires to the O2 sensor are grounding as well as the BL/Y and BL/G to the AMM.(according to chilton pg 6-42 diagram 8). The Pink goes through fuse 11 to a MAIN RELAY and BL/Y goes directly to the MAIN RELAY. I can't find anything telling me which relay is which behind the fuse box other than the bulb failure relay.
I hope my sitrep was understandable but I just want my purchased parts to do there intended functions.

Thanks
