well i just changed my tps and wow what a diff. i have been playing with it (moving it around to get the voltage) but my car is sitting on jack stands right now. replacing front end (struts, tie rods, swaybar bushings, rotors, and tires). but i cant wait till its all done so i can drive agian. just ahve to tighten down strut knuckels and get tires and im good to go.

right now im stuck driving my dads taurus. i hate fords, but dont get me wrong its a 2005 with only 19k on it

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?

Its really easy once you get the TPS off.

Ok i know this thread is extremely old...but

has anyone ever had the car running (idle) and moved the TPS blade and not the throttle and see what happens? Im very interested....i just cant do it on mine cause i have some tube PCV im thinking in the way...

And how did those adj mods go for the rest of you?

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?
