I finally got around to pulling the codes from my '93 yesterday, and there were a handful.
113 (IAT was/is open)
176, 177 (Left o2 not switching, rich/lean respectively)
332 (EGR not responding)
524 (problem in low speed fuel pump circuit)
543 (fuel pump monitor circuit shows no power)
And a couple more that were user error during the test. The car runs and drives, so I know the fuel pump is working. So I don't know what is up with the 524 and 543 codes. That might be from messing up the test on one of my earlier attempts. I did disconnect the reader while the car was still running and it almost died, so that might have thrown those codes.
IAT code was KOER, so it's probably not an old one from forgetting to plug it in. I just cleaned out my garage, and I had an IAT in my hand, the question is, did I throw it in the box with all my other old mark 8 crap, or did I throw it in the trash with all the engine covers and underhood plastic trim crap. Same with the EGR.
EGR code came up KOEO and KOER. I did have an EGR around from my '97 (if I didn't toss it), are those the same gen 1 to gen 2?
Looks like I need to buy an o2 sensor, throw an IAT and EGR at it if I have them around, and retest. hopefully the fuel pump codes go away on their own. If not, well, as long as the pump works, whatever.
