E4MC? Have to remove the airhorn on the carb. TPS is probably bad or the spring under it is fubar.

Re: Tps Stem stuck
I had the airhorn off,thats when i noticed it was right in.As i said it doesnt seem to be seized or bent,it just wont come up.Seems like it got a WOT signal and stayed there.

Re: Tps Stem stuck
A new one is inexpensive. Any auto parts store, AZ, etc. will have one.

Re: Tps Stem stuck
It's a sealed plastic unit and is probably gummed up with varnish on the inside. Soak it in solvent to try to free it up, but make sure it still functions correctly before trying to re-use it.
I've also found that a stronger spring is sometimes needed beneath these pieces once they get some years on them. Again I suspect varnish accumulating inside the unit begins to interfere with the free movement of the TPS stem. Probably your case at the extreme.

Re: Tps Stem stuck
I thought of trying that,but i read somewhere that the tps is one of the things that should'nt go in solvent,or can it?.Also can it be tested off the carby and if so how?.Thanks for your help.

Re: Tps Stem stuck
I'd really recommend a replacement if at all possible.

Re: Tps Stem stuck
The real GM replacement TPS sensors are not cheap- about $60 at my local dealership. But their plunger action is very silky and smooth.
I can pick up an auto-parts cheapie for $20. But the action is noticably scratchier and clunkier than a real GM unit.
I've used both with success. But when it's something that really matters to me I usually cough up the big bucks for the genuine GM piece.
Both come with a new spring for under the TPS.

Re: Tps Stem stuck
i agree, GM prices are bad but they always work great!
I thought Australia had lots of GM stuff. don't they make parts there? maybe that's only the new stuff.
sorry off topic.
With my old camaro i just got sick of it and converted to the old system. Got a different carb, dizzy with vac adv. and you should get an aftermarket torque converter lock up too if you choose this. then again you could get lucky and find the spring?
