Eliminating possible issues

I had a chance to spend a little time on the engine this morning.

CCP at start-up :

As you will see from this video, initial CCP was about 2.6 PSI. (This is way out of range - ambient temp was 70 deg F. Max should be 1.95 PSI). What influences FP?

After about 14 seconds, it moves swiftly up to about 3.0 PSI. This supports that my TTV is operating properly (SkiVT - I have the WUR hose in it's proper location on the TTV).

I drove the car for a while - maybe about 10-15 mins or so, and noted the FP - 2.65 PSI

I then detached the hose going into the AAR, and took this Video:

This supports that my AAR is closing as it should.

My initial issues remain as they were; low idle at start-up, dropping idle during warm-up; stalling/almost stalling when out of gear.

So I think that I have at least eliminated the TTV and AAR as issues.

Tony has graciously offered to test my WUR, which I will pursue.

Any thoughts/comments?
