can't adjust your idle. It's done by the computer. Don't mess with it because you'll pay for it like i am. I messed with mine and i still haven't be able to get it just right. If you look under the hood it'll state that the emissions and idle is controlled by the computer. sorry....only way to udjust the idle is with a chip or a tune.

You can adjust the idle. The screw is covered by a glue or cap and is moved with a small allen wrench. It's to the right of the the throttle cable.

Only temporarily then the computer will learn and what you did will be useless. You can adjust it but it won't do anything after the computer learns it after a few drives. I wouldn't recommend touching it. But you'll live and learn if you don't believe me.

it won't adjust the idle though. the idle speed is controlled by a computer controlled valve. if you open the tb butterfly enough to let extra air in, the computer will close the idle air control valve a bit to compensate. the screw is there the open the tb butterfly to the point that it doesn't get stuck in the bore.

The size of the hex bolt for the idle adjustment is 8mm. That's what it is on my ATX anyways. Not sure if they would make it any different for a Manual or what-not.

Cheers!

size of the screw doesn't matter...crazy stated its purpose. Its not meant to increase idle, i tried when i first installed my throttle body. I had it idling at 1000rpm until the computer relearned and threw a CEL because of the IAC....

what exactly is the iac? i have a fc tb and the cel waited at least 3 weeks to come after the tb was installed. is it possible that the screw on the tb is causing this?

I had to adjust the screw to make my TB not stick, I wouldn't call that changing the idle , more like improving Butterfly reaction. But I had to adjust it once, now my car idles like a fricken champ. It took me a couple of minutes of screwin with it but since then no problems.
