Car Stumble Issues; PO102 Code
The issue with my car had nothing to do with the transmission. We started out with a lean bank 1 code being set and then added in a MAF sensor code. I got a replacement MAF and cleared codes and drove the car; still has a stumble issue at times; but not above 2000 rpm. It also seemed as if it was a miss so since I had them on hand, I replaced the coils, the ignition module, and the ignition wires. No improvement. We pulled the IAC from the 93 (not sure of the changes between 93 to 98 in the IAC). No change. We put the old MAF sensor back in and the car drives fairly well with a stumble now and then. Now with the old MAF sensor it trips the 102 code; the new MAF does not. By the way, the lean bank 1 code has not returned (we did do a vacuum leak check on the hoses) We are thinking that the new MAF is bad. Now here is something that I thought the PCM would not do. More than once with the old MAF sensor in we have seen the CEL light go out only to return. I thought the car had to be driven X number of miles (I was told 100) before the PCM would clear the code.
