I believe it is the AIR check valve for the passenger side. It is mounted behind the intake manifold and is a pain to get to. The drivers side valve is easy, the way it should be. I found a thread where you remove the hose from the drivers side that runs back to the passenger side valve and spray a bunch of WD40 in it. Then blow it on through with compressed air to free up the valve. It worked for me.

Yep!! Try the cleaning first. It works most of the time!

Here is a picture of it on a mock up C5 chassis:
