The car will start and idle but as soon as you rev it up it feels like it runs short of fuel or air. The car throws a code 34 which is low voltage to the map sensor. With map unplugged it does the same thing. If i pull the tps the car will idle and stubble a bit when give it gas but will rev!!! Does anyone have a clue on this? I have switched the complete wiring harness thinking it was in there but had no luck with that. Tps is okay i took my tps and put it on another car and it worked fine
