Idle Problems, Out of ideas Options

[nightryder]

So Ive been having issues with my idle for quite some time now. For a while it was bouncing consistently between 1800rpm and 2200rpm. so I swapped throttle bodies (i couldnt get the iac out). so problem solved! its no longer bouncing, now it is stuck at 3000rpm.


So I pulled off that throttle body and because I had the new screws I forced the screws off my original tb, cleaned it and put it back together. same problem.


I dont know what to do anymore, I'm stumped, any ideas are very much welcome.

sounds like the IAC is stuck open nate.
break the screws off the old TB, and clean out that valve we talked about yesterday at the garage.

i actually thought of that, and I did it, with the same result.


Now when its "idling" if i give it a little gas, it will stick at whatever rpms I put it to, then drops.

have you tried the BGB tests for the IAC?
you can get them in the sticky in the general dissucsion sticky at the resource site.

IDK if you have seafoam there but you may try that if you do. I had the same prob after i got my car from the shop, but it does idle as high as yours ~1.5k rpms. I just sprayed the throttle opener with carb cleaner and it worked.

I wish it was that simple! i sprayed the hell out of it and still nothing, im kind of at the end of my rope here. ill check out those tests tho.

Man, i know what u feel.. It pisses me off when i try to stop, push the clutch in and the idle stays there... not cool

[nightryder]

so ive gone through everything I can think of. Anyone have anything for me?

Just trying to help I had a post a ways back. My idle was fluctuating and I found out it was the airbox sensor wire. It seems to be where the wire for it meets the harness right next to airbox. I tiestrapped it firmly and my idle works perfect now. But when I would just barely move the harness or the engine would shake the engine would make a strange sucking sound and idle would jump. I still have to go into the harness but I don't want to mess since it works perfect now.

Edit what I was trying to say if you wiggle the wire where it meets the harness and the idle changes it can be the problem that I have ,if you wiggle the harness and nothing happens then your harness and wire is fine.

Check it out.

ill take a look, are we talking about that kinda cone shaped sensor that plugs into the airbox?

[presure2]

yea, tahts what he's talking about nate, but from what your discribing, that dont sound like your issue.

disconnect the throttle and cruise control cables and start the car. could be a stuck cable not returning well and causing the high idle.

i did try the throttle cable...hadnt thot of the cruise control tho. ill give that a shot. thx man

[nightryder]

ok so I gave the cruise control a shot...nothing...


you guys think it could just be a real bad vac leak? I have no idea where it would come from, but i keep coming back to that

[presure2]

nate, does the car run?
if so, gimme a call, and we'll plan a day for you to come down, and we'll trouble shoot it till we find the problem.

[nightryder]

it runs, but the rpms stick @ wherever they are revd to otherwise they stay at 3k+....



ill b in touch

So what did the problem turn out to be? Any updates? I'm suddenly having major problems w/my motor - similar but not the same, and I'm looking for ideas.

[95CelicaST]

Check your distributor shaft for play. I had bad idle problems and it turned out to me the distributor.

[GriffGirl]

Mine seems to be more like an airflow issue... I'll start my own thread though.

i had the same problem. i tapped on the valve with a small hammer while spraying it with solvent and then tapped on it while spraying it with wd40. it fixed the problem
