Throttle stick in between shifts please help

[92CamaroRS]

I have a 92 camaro 3.1 v6 manual. In between my shifts, when i push the clutch in, the throttle likes to stick open at about 2000 rpm and will stay there for abou5 seconds until it eventually returns back to idle. I had an idle air sensor motor changed but that did not fix the problem. can someone help me?

When you say stick open, Do you mean that the pedal is sticking down? Or the pedal returns and the idle stays up??

[92CamaroRS]

the pedal returns but the idle stays up

[DaMoNe6969]

alright.. sounds like a bad or misadjusted TPS (throttle position sensor)

Could also be a vacuum leak in your system somewhere.. WHen you rev up the engine, do you ever hear whistling noises??

[92CamaroRS]

yea i was under the hood and was revving a bit and it was whistling a bit on the passenger side

[DaMoNe6969]

Have someone rev it up a bit and listen through a length of pipe.. Try to pinpoint the whistling noise.. A bad vacumn leak will cause the high idle.. You could also try squirting soap and water on all the hoses and connections (EGR hoses, PCV hoses etc etc) Look for bubbles

welcome to the forums by the way

ok. i actually just looked and there is a fairly large leak from my idle air hose, the hose coming from the beginning of intake into my valve cover

if you do plan on changing the TPS, i have some advice. use the right size tool, cause the bolts will
strip out.

That sounds to me like PCV system?? I could be wrong.. at any rate.. Fix it! lol let us know how that goes for you

[92CamaroRS]

hey thanks. where exactly is my tps?

[DaMoNe6969]

it'l be on the throttlebody at the end of the throttle shaft.. Kind of a round lookin thing with two small torx screws holding it on and a three or four wire plug in it..

[92CamaroRS]

ok i removed the tps and there is a spring wrapped around a metal shaft is that supposed to move freely?

[DaMoNe6969]

yeah that should move freely (it should only be able to move in one direction, then return.. but there should be very little resistance..

[92CamaroRS]

wow. ok because that was half open and when i push it, it doesnt spring back and it also has quite a bit of resistance
