I am having the TPS code thrown at me and rough engine when I hit the peak of driving at a steady speed. i ahev taken the throttle body off and tested the TPS itself.35volts at idle and 5.2 volts and max. I am pretty sure that si within paratmeters but cant find exacts. I have a Haynes and a FSM iwht no notes in either for exact specs. Also when i tesed the wires with disconnected from the TPS and ignition on (key turned fwd) I have three cables runnign to the TPS connection, a bright orange, bright orange and black striped in the middle and then a brown and yellow striped. from what I can gather the brown and yellow is ground, orange is power 5 volts, adn oraneg and black is the signal wire with a 4.6 volt on the meter. There is my other question, should the signal wire from the TPS be reading 4.6v with the igintion on and no TPS connected? Is it somehow gettign juice/power from somewhere else by accident? Any help would be greatly appreciated.
