Obviously that didn't help,so I guess you need to replace them and see what happens.

It seems that whenever I've cleaned an IAC I've killed it. I don't know if I accidentally push them in or nuke them with cleaner, but they never seem to work right. Your best bet would just be to replace it, IMHO.

Where is the IAC valve located? could someone post a pic or something cause I've never dealt with them b4 and was curious of how to clean it.

The wire that plugs into the back of the throttle body hooks up to it (firewall side). It's held in by two T-25 torx screws. Very easy to replace.
