I just installed the accufab upper intake plenum and the accufab throttle body, i took off all the sensors and vaccum lines and plugged them back in, but when i put the tps back on i just threw it back on with out checking the voltage. we were trying to set the voltage but it wasnt reading anything, then the check engine light came on. right now it likes to hang a little bit around 2000 or 1500, it needs to be at .98 volts but how do you get it to .98 volts? just throw the tps sensor on and try to adjust it with the idle screw? do you need to adjust the tps BEFORE you put the sensor on?

does anyone have any pictures of how they did it or any good instructions on it? thanks

When I did my TB/Upper Intake Plenum combo I didn't adjust or check my TPS voltage on my GT. My RPMs did hang but it was because my throttle cable was getting stuck on one of the vacuum lines running out of the back of the UI Plenum. I installed some washers underneath the bolts for the throttle bracket. Problem solved.

You can loosen the 2 bolts on the TPS and their is just a slight amount of play to turn the TPS right or left. That should adjust your idle by a small amount and help with the up-idle problem. It took my car a week or so before the hanging idle went away.
