Hey guys, new to the forum. I have a '95 with a 5.2 automatic. It suddenly doesn't want to start, it will start sometimes but it runs terrible and won't rev up, you can sometimes get it to rev up a bit but you can hear the intake pulling air it just won't rev up much. It really seems like a plugged exhaust but i had it off and it made no difference.
I have checked coolant temp, iat, cam, crank, used a test light to check injector pulse and it seems good, good spark, good timing, fuel is good, fuel pressure good, map sensor voltage changes when it does run so I think it's working. tried another PCM and no change.
I changed the oil after this happened, filled it to the top of the range, checked it yesterday and it's way overfilled and smells like fuel. Plugs are new but are blackened wet with fuel. This makes no sense to me. It seems like I have 8 injectors that are stuck open...........
Any ideas are much appreciated.
