I have a dilemma with my 94 4wd xlt.
Started running very poorly and bucking at about 1/4 throttle. I managed to get it home by idle. I could not event hit the throttle at all, I was like it had a bad fuel filter.
SO, I checked the codes looks like a bad tps, bad IAT, and a bad O2 (Always lean).
I have replaced all of them and the fuel filter, cleared the codes and NOW I have codes 114 and 116 and hard codes 172 and 176.
So, the IAT is reading hi/lo, the coolant temp is taking longer than expected, And I still have an Issue with the O2 sensor being always lean.
Do I have a bad MAF sensor? Or a bad ECM?
I have been farting around with this for over a week... It's making me crazy!
