TPS voltage way to high at idle...Please help ASAP. I tried slotting the holes to lower it and it stays in the high .80's. Even if I remove the screws completely and rotate it i can only get it to .70? (An inch from the bolt holes!!)This is a autozone replacement. I have a nick willams 90mm cable driven TB on a Ls3 intake. I cant get the IAC below 114 at idle either. In HPtuners wither we can get it a 2% tps at idle and only 78% Wot. Or adjust to get 100% at WOT but it stays at 23% for idle. THis is killing me!! I want my car to idle! Also at WOT the TB blade is all the way open.

Going to buy another TPS sensor. I searched and couldnt find anyone on the forums that had the same problem. I can completely remove the sensor and manually turn it and the lowest it will go is .70. Also at idle it showed 2-3% even when we reset it. Never could get it to zero.

I hate to bring a thread back from the dead, but this ended up being my issue as well, so a big thanks to the OP for posting a solution. My Car is a second gen RX7 swap, and the ONLY thing I did not do myself on this car was make the engine harness. So much for paying a professional and avoiding the headaches. A quick harness check (after some pretty intense troubleshooting), revealed the TPS was sending a true .88 volts at idle (limit of the TPS sensor) and that the ground and signal pins on the TPS reversed. swapped it around and I am now getting 0% at idle and 100% at WOT. Idle tuning, here I come.
