I don't think there is a vacuum hose on the IAC, just a harness connector.

I assume you mean the Throttle Body

There should be an emmissions sticker on the underside of your hood with a vaccume line diagram, also one in the Tech Section or just consult a Haynes/Chiltons manual.

Each OEM vacume line has a different stripe (Yellow, Red, Green..etc) so clean the hoses off first with some solvant and then consult one of the above.

BTW.. with my EGR valve disconnected/blocked off I get a bobbing idle that settles down after a few cycles, but with it connected it idles perfectly
