so what gives on the TPS adjustment? i have read in here that you want about 4.6 or so volts at WOT. why? if the PCM resets the TPS to 0%, why bother? how about closed throttle? what kind of numbers are we looking for here?

 

Um, I think you have some mis-info there. 4.6V at WOT, and about .90-.99 at Closed throttle. Honestly unless you vehicle was 10-15yrs old I highly doubt your TPS is out of whack...look for power elsewhere.

 

that's like, what i said or something. i was just wondering what the numbers should be. i know GM has some kind of spec on this. you have answered my closed voltage question though. thx!

 

My blade was not opening all the way so I used a dremel on the bumpstop until it read 4.6v. Now it opens 90 degrees perfect. I don't know if this has anything to do with your question though but I think it might
