When I get the chance, thought about tweaking the orientation of the tps when installed to see if it helps any. Did you do anything differently when you installed yours?

So I was toying around with the tps and unbolted it so that I could maneuver it around with the car running and when I twisted it towards the passenger side, the idle came down. So seems like a voltage issue to me. Figured my options were to wire in some resistors or mod the tps bolt hole so that I can crank it back to where I want it and have a decent idle. Opinions?

I wouldn't be surprised if that were the case.. I found the stock voltages for the tps and plan on going out with my multimeter to see what they are.. hoping that is the issue so I can go from there.

So I found this while combing through the forums earlier:
MAX voltage at 100% throttle is between 4.25-4.8 V. It should read between 0.25-0.8 V at idle. Power input to the TPS should be between 4.8V and 5.2V.
With that being said I checked the voltage at idle and it was around 1.0 and at max throttle was around 4.6.. when I tweak the tps sensor orientation the lowest it will go is .68 and then max throttle is around 4.4. Looks like I need to widen out the sensor holes a tad and should be good to go.

I appreciate stockers response but the idle suggestion from faith wasn't straight forward..
But besides that, I've gotten the idle down from around 2k to about 1.2k at the moment. Need to bore out the tps hole some more and then should be good to go.

You dropped a hint, faith. As men, we are free to ignore hints and wait for plain language. For all any of us know, you were talking about a complicated electrical solution to shift the voltages, or maybe using a trained monkey.
a hint?
any piggyback/standalone worth a damn has a tps correction built in. mine was as simple as: press button. step on gas. hold. release gas. done.
since when is

fact that the TPS reads closed differently?
