ALL functions appear to be normal other than the premature loss of vacuum noticeable by the door lock issue I have currently.

I have so far replaced the loose 4-way rubber connector to the check valve and have ordered a check valve from the dealer.

FWIW, all these symptoms and malfunctioning started when I noticed oil in the pre-filter I installed in the shutoff valve vacuum line. I will be having the leaky shutoff valve replaced by a garage (concern about the runaway engine) soon. See what happens and hopefully should fix the problem.

Installed a filter on the line, recommended.
