I installed an explorer TB on my 91 GT and swapped the stock stang TPS right onto the explorer one w/o modification. I read that the bolt holes would need to be widened but it slipped on perfectly. How do I know if my tps is working correctly?

I ask because my idle is a bit funny. It idles at 1100rpm for a while then bottoms out at 700 eventually. I also put in a new h/c/i as well but don't think my idle should be taking so long so bottom out.

Check the voltage on it when it's in the key on positon. It should be around .98 volts when plate is closed.

Anywhere from .7 to 1.1 closed throttle output voltage will be fine. If you want to check if the system is working with a TPS related failure, run the DIY KOEO/KOER/Cylinder Balance Self-Test and LUK.
