ok so i think i have it narrowed down, because i can't get a voltage reading out of my tps or the reading wont be nearly as high as it should be, so one more question,........do i have to adjust the new TPS after i plug it in and screw it down? and if so where do i adjust it at?

 

'91's are non-adjustable. Consider yourself lucky. The adjustable ones are such a pain.

 

Not really.
I just always adjusted to either 0 ro full. 0 is usally easier though.

Close throttle. Put on TPS. Hook up Multimeter. Adjust TPS untill you read a + signal, then back it back to 0.
Usually 5 minute job.
Works great on import cam sensors too.

 

You ever had to adjust one on an 80's 3300 Buick? NOT FUN

 

Have you ever had to adjust one that was involved in a motor swap that took a FWD engine and put it in RWD config and you were lucky to fit a pencil to the cam sensor? or better yet ANYWHERE behind the motor?
THAT was fun, but still only took about 20 minutes. Most of it was dealing with the bolts. Tighten and move the sensor, start over, tighten, move the sensor start over... Yeah one of those.

 

well i got the sensor,pulled the old one, placed the new one, put the lower bolt in, went to put the upper in and it seemed to be hand tight, so i went to torque the otherone down and click, dead screw, so backed it out (thank you mr. vise grip) took out the other one, turns out it was cross threaeded anyway, so now i'm off to lowes see what i can do, DAMN YOU SCUBA STEVE

 

ok ok so i got the new one on, car runs a little bit better, will have to do more road testing, but now it wants to idle at about 1500 what is going on here??

It's from the tech articles here. Also it's good to have some testing equipment if you don't have a DVM. I think all the autometer garage sale testors are sold out (haven't checked in a while).

THis is what can happen when the TPS is outa whack:



black soot out the tail pipe. not good

 

You're NEVER working on my car. Do you realize just how out-of-spec that is?!

 

i was told that for 91-92 mpfi 3.1 there is no adjustment for it, matter of fact = so now i'm confuesd

 

I have a 92' Firebird and the TPS is not adjustable. Just 2 holes to mount the TPS.

 

the adjustable TPS has slots where the screws go in so the TPS can be rotated adjsut the voltagge readings.

 

Conused about what? About the years? 1990-1992 thirdgens got non-adjustable TPS.

 

i was confused because i thought he was talking specifically about my car......so now why would my car chose to idle at 1500?

 

Do you realize just how many cars THAT IS SPEC ON?

I was saying that for referance. That is a way you set them correct? you have the throttle body closed and set it to the lower reference? Thought so. Go away.

And I do not.. well I will just stop there... YOUR not worth it...

 

It's not for V6 Thirdgen F-bodies... and that's what counts here.

If you're going to state numbers, attempt to state accurate numbers, rather than misinforming new folks on here who likely respect your technical experience and take your word at face value. Idle TPS for most GM EFI engine management systems is optimally between +0.54vdc and +0.56vdc, *NOT* zero. Zero would throw a code 22 and likely (IIRC) force the ECU into limp mode.

Also, throwing hissy fits at people just because you don't like being told you're wrong... not a good thing.

 

1. I never said it was spec on a third gen.
1a. The question was about a TPS. I gave what is easier way to adjust, if needed. It is the persons own respondsibility to know the spec. I do not have those numbers in my head. That is what books are for.

2. I did not throw a hissy. I made a statement that dealt with your problem that was posted.

3. I do not act like I am the end all of all automotive knowlage. When I have an idea, or a strong hunch, I post it. People asked how do you adjust the TPS, I gave a suggestion. I say do it with the TB closed to the stop point, because alot of books say to adjust it at full open, which is a major PITA.

As far as you being a moderator, I could care less. If I or you have a problem with something the other says there are appropriate ways to deal with them.

You calling me a bad mechanic is not one of them.

 

If you post it on ThirdGen.Org, one assumes you intend to call it spec for a ThirdGen, considering that's all we deal with here. And while putting the responsibility on the owner to look it up in a book is logical and easy, alot of people turn to TGO as "the book".
Your proceedure was spot-on. GM EFI TPS is adjusted at idle. WOT adjustment is actually somewhere between unadvisable and impossible. The only problem was your use of '0'.
I'm not calling you a bad mechanic. If I were calling you a bad mechanic I'd say "you're a bad mechanic"... I would not refer to people looking up to your experience. *That* infers that you have experience worthy of looking up to, but managed to post one bad number. A single digit, no less.

Side note.. this is sad. We're arguing over nothing. Literally.

 

nahh maybe i should have specified on the THIRDGEN.ORG board and the V6 sub board that i was looking for information on my V6 THIRDGEN based car my fault!!!

 

ok ok, another questiong, after replacing the tps my car wants to idle at 1200 while driving and 2000 from cold (i think thats normal) what i mean is when i start my car it idles at 2000 and then while sitting at a redlight its at 1200
