Well certainly have me and everyone posted if you come up with something. I pretty much love this car except for this on-going issue, I've dumped thousands into it with no luck.

I actually replaced the sensor. I replaced everything that affects A/F ratio, and then some. I also done some experiments with the ECT sensor by unplugging it and plugging different resistors instead to fool the ECU into supplying more fuel, and it seems that with restance that normally means 60 degree when the engine is actually at 80-90 degrees, the car has much better acceleration, but it pings like crazy.

 

it maybe good new for u in here


i change back my old altenator (it only charging 11.4 v bad) bc autozone did not have one yet so i have to wait until tomorrow

but i swap the old on back it run fine no problem idle fine every thing run good but it only charge 11.3 v have to ait until tomorrow swap a new one in , and wait for few days see anything going bad................

It was The EGR system..

 

What specifically on the EGR system? I experience a similar problem with my 93 sometimes as well.
