I will have to get under the foot-well later and see what I see under there.
As far as the vacuum issue, I've gone ahead and removed the passenger side headlight to expose a commonly cracked vacuum line, but it seems OK.
I also traced a top-side HVAC vacuum hose to the manifold and again see nothing worn or cracked. I took a couple of pictures as the small vacuum line plugs into a larger hose which has some kind of diaphragm between it and the manifold. Could this disc be the culprit as far as the vacuum issue?
