Hey guys, I have a question about TPS voltage on my 94 Pontiac Sunbird. I have a REALLY bad hesitation when I put the pedal to the floor, she bogs dwon pretty hard. Anyway, I figured that I would check my TPS voltage. Wth the key on engine off with the throttle closed, it sits at about .37 V and at WOT it is at 3.9 V. From what I understand, I thought that most GM cars liked to see .5 V at closed and 5 V at WOT. So I removed my sensor, elongated the holes so that I could make it adjustable. I adjusted it so that it is at about 4.75 V at WOT, but when it comes back to closed it sits at .82 V. Is this OK? I figure that it's making the engine run a little richer. The hesitation isn't nearly as bad now, and I don't really have any more bogging of the engine unless I'm in 2nd gear(it's an auto) and I give it less than 1/2 throttle. What I wanted to know is does anyone have the factory manual for a 94 sunbird 2.0L that can tell me what the correct TPS voltages are supposed to be? Thanks for your time, Paul Moore.

All this, and I still can't go fast.............yet!!
set it so its about .55 at closed throttle, and it should be about 4.5 at WOT. anything above 4.4v is considered full throttle by the ecm.
Awesome, thanks! I will readjust it as soon as humanly possible.
