So I have been having TPS problems for about the past two weeks. I went to the junk yard to get a new one got two of them. One of them was from a RX one was from a wagon turbo (had a dirfront plug on it). After trying the one from the RX it worked for a while then started acting up damit. I chopped the plug off of the TPS I took off my car and wired it up to the TPS from the turbo wagon. That one worked for a while then started acting up again I know this one works so I tryed to change the mounting position of the TPS I turned it clockwise all the way problem got WAY WORSE. Ok I think I figured it out I changed the mounting psition again this time almost all the way counter clockwise maybe 75% and OMG all my throttle problems are gone I can drive with out my sudden power loss.

MMMM How is the fuel economy now? if will be getting more fuel now so if its using heaps of juice..send it back a little..this is fine tuning...cheers

Good job!

I will try that on my 89 today.

here is a way to "recondition" your existing TPS:

I dont think I am using any extra fuel. I cant realy add it up since I dont have a rear O2 sensor in my exhaust my fuel economy is down becuase of that I will be getting one in any day then I will do fuel enonomy tests. I can say its running ten times better than it ever has. Like the post on link says make sure your TPS is bad before taking it apart I would make sure I have a extra one before I opened the one from my car.
