That vacuum switching valve with the exposed nipple, heheh, is for the airbox flapper. I can't recall the diagram/routing offhand, though. And, it's 115am, sooo....

Get it back together, drive it a bit and let us know if there are any new symptoms or if the same ones remain. It sure can't hurt it to have vacuum lines where they go!
PS - When I bought my Vibe, the vacuum lines were ran incorrectly. No check engine light or anything. Thank goodness for vacuum line routing diagrams! I never see other GTs or XRSs to compare to.

That is what I was going to look at next. Is the IACV the device I unplugged that is directly beneath where the throttle cable attaches? Know of a way to test it rather than just replace?

I am sure you can find a good used one.
In general, how hard is it for my mechanic to look for a vacuum leak?
