How do I adjust the d#$n thing? I found several people willing to sell me theirs, but I would rather fix mine. All I need is a pic or a GOOD explination of where the adjustment screw is. I know how to check the volts and all, I just can't find the screw!!

 

Turbo or no?

 

N/A. It's a 1991, so it has the 2 plungers, not just one...

 

There should be an adjustment screw on the front of the throttle body. Take a close look at the linkage that pushes the plungers on the TPS in.

Run a quick search for "TPS adjustment" or something similar, this is talked about a lot and I'm sure there's plenty of good info. I'd write up some instructions for fine-tuning it, but I'm kinda busy today.

 

http://home.rmci.net/panther/tps.htm or read this and especially the answer by Keith, who is really Irv https://www.rx7club.com/vforums/show...threadid=25310 while you mull that over read this site from end to end http://rx-7.cep.net/FAQ/faq2.html#14 All read? Then the best method is the one by Irv.

 

Just curious what the problem is with the TPS?

 

Well, for starters, the car idles rough when cold. The RPMs jump from 1200 to 1500 RPMS. Dave @ FC3S.org told me this is called hunting. Also, when I decelerate, i.e. let off the gas, the car falls flat on its face. It jerks pretty bad. It just feels like the gas is being completly cut off as soon as you let off the gas, and try to maintain an even speed. Dave said this is all due either a bad or poorly adjusted TPS.

 

Hmmm mine does the rpm bounce when cold, craps on decel, at idle the rpms bounce between 550-750 (not too often) and I get a check engine light whenever my foot is completely off the pedal. I also get occasional hesitation on accel, mild bucking. I just decided to buy a new one. Not cheap for me (TII) but atleast it'll be brand new and it shouldn't go bad for a long time

 

I fianlly fixed it! My car idles so awesome, I am no longer embarassed to let my friends ride in her! Thanks to all of ya!
