Idle Air Control Valve

Is there a procedure to installing a new one, some adjustment that needs to be made, etc, or can I just pull the old one and install the new one?

generally you just remove the old one and install the new one but sometimes you may have to clean around the throttle plate and disconnect the battery to clear the idle strategy so the computer will relearn it.
about all advice I can give you without knowing specific make model year but generally it is just a direct replace.

Definitely should post your year, make, model, and engine size to make sure...but like bejay says, it's usually a clean swap w/ no special procedures on most vehicles.

BTW, that can be a very expensive part on some vehicles...any particular reason you are replacing it?

It's a 97 Jeep Cherokee sport with the i6 4.0, automatic, air.

The idle is fubar on it, and I suspect the IACV because it does _nothing_ when you flip the ignition. All the ones I've seen retract (open the valve) when you first turn the ignition on.

Nope...no special procedures. Unbolt and rebolt.

Just thought I would follow up.

Got the new IAC servo today ($45). Only adjustment was making sure the pintle wasn't 'more the 1 1/8" out or internal damage to the IAC servo may occur'' before installing. I adjusted it in and installed. Started up and idled normally. I didn't drive it, so will find out for sure next time I'm out if it's truely fixed.
