Looking at the hose connection plan in the manual, this part looks like it allows air to pass from IC to inlet manifold under certain conditions.
I presume this is only when engine is cold? I can understand how this might cause revs to stay high if it was stuck open.
I have another car to swap parts from so I'll swap AARs tomorrow to see if this fixes the problem.
While it would be nice to identify the problem, my heart is hoping that it is a leaky hose somewhere rather than a $974 part.
