This thing is making my head hurt!!! Pulled the code and getting a code for bad TPS. I changed that out and then moved on to the throttle body and cleaned the MAF sensor. Wires all look ok. Car idles ok, little rough, but it will not rev over 2000 rpm. Push on the throttle while driving and it does nothing!!! Maybe a fuel pump? I need ideas, got any?

Follow the diagnostics in the fsm. If your puling a code for the tps, then its likely the signal the ecu is seeing is not in the expected range. The diagnostic profit should help you isolate it.

Did you replace the TPS itself or the whole throttle body? The TPS isn't meant to be serviceable.

Replaced both. Anything mechanical I'm really good at, but electronic stuff you'll have to dumb it down a little :)

yeah for the most part a relearn might take once or twice to do, my car hates to take it the first time, but a tps code will throw your car into limp/failsafe mode so you cant rev past 2000/2200 rpms. like jimmy said, start with voltage and make sure theres no break in an exposed wire or something stupid..
