I did some research on the different TPS types. As previously discussed there is an adjsutable TPS that covers Bonnevilles from 1989. The Standard Products part number is TH50.



The non-adjustable, 1993-On, is part number TH113. They probably went to non-adjustable TPS types to prevent "tampering".



Hope these images help.

Maybe it'* just me , but this TPS mod sounds kinda complicated. Or will this make more sense when I get in there to do it?

Nothing happened in my car; I moved mine accidentally while adjusting the TPS.

As a follow up: I currently have this TPS on my car. Was initially giving me the idiot light, but I just went back down stairs and reseated it. I'm now getting the performance boost without the idiot light.

As a follow up, I wouldn't put a used TPS of that age on my car, and I personally don't like the TPS enhancement on an OBD1 car with a 4T60 trans and shift kit. It'* too sensitive with regards to TCC lockup/unlock. And that causes wear and tear. More throttle response IS a slight benefit, but the TCC issues aren't worth it. Mine is back to the factory setting.

I just wish I could figure out the weird readings on mine. It shows a neagtive voltage (-)for all the meter readings. At idle, the meter shows the reading for WOT and at WOT the reading for idle. The strange thing is the car runs fine too, with no codes.

I should check mine out to ensure it'* working properly. Nahhhhhhh

Do need to check my scan results and might as well. Voltage on 97 SC should be 0-4.7 right?
