TPS (Page 1/2)

So I just bought my new TPS feeling very excited to get my fiero to be normal again…. Well I plug my computer in and the new TPS was reading 5 volts off! It is supposed to be at 0 or -1.25 volts. What is my problem here? I know it’s the right TPS because I ordered it from Rock Auto. Please help!

Well forget I posted that…. Come to find that I had gotten a TPS for a 1985 4.3L Monte Carlo…

I just replaced mine and had to bend the arm on the new TPS to get the voltage up. My was a Delco for what that’s worth.

It's a whole lot better to rotate the TPS rather than bend its metal arm. If the TPS didn't come pre-slotted, it's pretty easy to create slots in the plastic housing.

I put my new TPS on. It ran well it idled and didn’t die in gear. Then I let it idle for about 10 mins. I come back an hour later to start it to check the voltage and the voltage is right but now it is back to the same problems it had before. I really don’t Understand and it sounds worse

Does anyone have any idea to why my fiero is still acting up? It was working fine then went back to its same problems as im about to list: can’t idle, dies when put in drive or reverse. Doesn’t sound well either. Much help is appreciated

Try replacing the ignition coil and ignition module with AC delco parts

I will have those parts come in tmw and inform you on any difference

I replaced the ignition coil and the ICM….. still same problems. Should I try figuring out how to do an EGR delete?

I’m running out of possible solutions. I don’t want to have to replace everything that is a possible problem but it seems I’m already heading that way.
