Did you do your own swap?!

IACV does not need vac lines. Try unplugging it and see if the idle changes any. If not the it is not wired properly and needs to be..

Yes, the IACV has coolant lines that run to and from it, not vacuum lines.

check your throttlebody gasket if it's not the IACV,but make sure you eliminate electrical connections,vacuum leaks,bled the cooling system,etc before you pull off the T/B.If you remove the T/B be careful and don't rip the gasket,pull it off and make sure it matches the ports/holes on the T/B and that it seals around the entire surface of the T/B.
