Default Hanging Idle.... out of ideas.

Mods are in my sig below. I recently have been having a problem with the idle hanging, whenever i would push in the clutch after driving they usually jump to about 2k and hang there for about 10 seconds before dropping. I replaced the IAC and it seems to only have made it worse. No trouble codes are throwing and i can't find a vacum leak anywhere. Any suggestions.

I was having the same problem with my rpms hanging. I replaced the IAC and it still did it. I just unplugged the IAC and it is fine now. Although mine would not do it when I depressed the clutch, only when I would rev it.

Try it to find out. Mine runs great without it, but my buddy's Bullitt will die if it is not plugged in.
