high idle.Not a noob question
Hey guys. I switched throttle bodies and now have an idle of 1380. The tps is adjusted properly. Even w/ the throttle cable off it is 1380. No vacuum leaks at all. Non sequential so I sprayed brake cleaner everywhere. No accel. in rpm from the test. The adjustment screw is all the way loose (not touching anymore). Large flat head adjustment screw (on bottom) all the way tight. The more loose I make the higher the rpms get. I have the warm up (wax rod) eliminated. Any help would be appreciated Garret.

If you've removed the whole unit including the adjustment screw for the wax rod, you should be fine. You do need to look at the angle of the butterflies in the TB when it is fully closed. They could be open just enough to raise the idle.
As for the leak test:
You need Carb and Choke cleaner.

When you replaced the TB, did you replace the cork gasket with the updated metal one, or was that already done? If not, replace it. That's another potential air leak

No it's not Turbo'd
I had a similar problem when I re-did my coils... there is a charcoal canister below the UIM, and it has several (2) tubes ging to and from it, make sure you haven't pinched it, even slightly, because that will cause the idle to rise.... also make sure that the tubing to and from that sucker are thick walled, when I had my issue, it was due to me swapping it outm, and due to the vaccum it sucked itself shut... = High Idle 3-4K rpm

Thats one of the reasons my throttle body it still not polished even though I have a spare on the side. Well, my idle got screwed(2k rpm) even after I mated my original tb to a polished uim. I was thinking vaccum leak all the way, but it turned out to be the isc. The rod was stuck with a slightly opened butterfly plates.
