I discovered the first issue at the hot
water valve
the hoses around the time relay delay were
leaking a little bit
for testing purposes I hung a spare master
vacuum switch into the car - this solved
the problem
the old fast idle diaphragm was leaking and
brittle and was replaced with a better
one...

Vacuum Schematic from the shop manual -
1968 is almost identical BTW... Click on

there are lots and lots of vacuum hoses in
the Eldorado to check - here are only a few
going to the storage tanks...
I will also give them a good cleaning
during the winter.
the new hose with the painted red stripe is
already in place - looks some kind of
original...
