hey what up. i just got back in from Cleaning my IVAC with some TB cleaner. <stp stuff . I took it apart, took a few sensors off , and rinsed a whole can cleaning that out. Yeah it was black/
Anyway , if you just wanna do something free that takes about an hour thats the job. The Car runs much smoother now, and idle doesnt seem to drop and lope at 500 rpms as much. btw. it costs $2 to do.

Some would tell you to pay the dealer $460 (), while others would tell you to check the stickies. I'm am of the latter camp.

The IACV is what the pink, purple and gray connector are plugged into. there should be three bolts, in a triangular fashion. one of the bolts may be hard to remove becuase something else is in the way. you must remove that "something else" (just some metal plate that is bolted down). make sure to reconnect all plugs when done.

Here are some instructions I saved from before (not sure who wrote it):
------------------------------------
Tools needed:
10 and 12 mm sockets
3 inch socket extension
universal joint (swivel pivot socket thing)
12-inch ratchet (a short ratchet may not work - need something to apply a lot of torque to loosen the bolts
Philip's screwdriver
rag
throttle body cleaner

1. Unplug the 4 connectors from the IAC assembly. Undo the hose that connects the IAC to the intake assembly.

2. The metal bracket holding up the gray-colored connector is blocking one of the IAC mounting bolts. Using a 10mm socket, remove the bolt that holds the metal bracket. The bolt is just below the purple connector - you have to twist your head and crane your neck around to see the bolt.

3. Remove the 3 mounting bolts using the 12mm socket. The lowest bolt may require the Universal joint.

4. Pull out your IAC valve and clean it w/throttle body cleaner, rag, and old toothbrush.

You may even want to separate the plastic valve to clean it more thoroughly. Use a philip's head screwdriver, but make sure it is a snug fight. It's on there tight and if you don't have a good fitting screwdriver, you could ruin the screw head.

Reinstallation is just the reverse of these steps. It may be easier access to the IAC if you remove the whole air intake assembly, but it's not necessary.
