i tried this and it worked amazingly, i was really annoyed by the hanging idle, and this fixed it completely. mine wouldn't idle at all with the 3/16 hole, so i bumped it up quite a bit and it worked great. it was $5 for a whole roll of gasket material at the local auto zone so i just cut out the shape from one of the oil quarts i used this morning. great tip

Awesome mod...finally got around to doing this myself. I ended with at 1/4" hole, $6 investment, and 10 minutes less of my time INCLUDING taking it on a test drive. Best part is that it's completely reversible.

Or you can go to Home Depot and buy a 1/2" copper pipe cap, drill a hole in it (start at 1/4") and stick it into the IAC feed tube--83¢ and no tools needed to swap it out...
It doesn't matter where you restrict the air flow--"a chain is only as strong as it's weakest link"...

very nice, Cliffy. As Usual. Will have to do this, I like the idea better.
OT, but I really like how you painted your TC and Plenum. I have the same ones, and might just have to follow suit and do that to mine. Either Black or yellow, not quite sure. Any tips?

COOL....
wtg coolaid worked like a charm...ingenious fix..couldnt stand the hanging rpm's just because of a smog thing..now when I back down I dont just coast I actually slow down, and the sound is better when I give it a short rev like the old hot rods...love it
