Re: Car wont rev past 3000 Help.
i dont know much about the wiring on a single cam engine but i know that when you install a harness or reinstall your old one, the clips only fit where they are supposed to go except on the throttle body (b series).The TPS and another one can interchange (iac?).If they're crossed then i know from experiance that it will only rev to 3000 then it will die.

Yeah, but it uses a completely different plug(on OBD0 and OBD1 anyways). I think OBD2 has a 3 wire IAC?

OMG....what terrible advice by everyone. I'm ashamed.
He is OF COURSE in limp mode. My guess is the ECU sensed boost and threw a check engine (Code 3 = MAP?).
In a 94 (OBD1) there is a service connector under the passenger dash on the right side. Find it...stick a wire in both holes of that connector. Turn the key to 'on' and your dash CEL will blink. Count how many times it blinks and let us know.
Then...pull the ECU fuse for a good 10 minutes (its under the hood in the fuse box I believe). This will reset your ECU.
Fire it up...if it runs right until you boost and then starts acting up...the map sensor is seeing boost for some reason and you need to fix this.
Check your injector connections as well...one may have come loose.
