Thanks for all the suggestions - not sure, but I think I found a problem
with my throttle valve switch.  I followed the test on page 24.59 of the
Bentley "Throttle valve switch, checking and adjusting."

I get continuity when I start the test, at idle.  Continuity breaks when I
open the throttle (continuity good at full throttle), but then when I do as
the manual says and "close [the throttle] slowly" - I get no continuity at
idle again.  I can only get continuity again when I open throttle and let it
snap back into place.

Seems to explain my symptoms since it says "warm engine will have NO fuel
deceleration shut-off or DLS function at idle" if gap is too small....

but I can't get any continuity when I "slowly" bring back into place

So what now?  How do I fix this?  Is it just a matter of adjusting the
throttle valve?  Why does it get continuity when it snaps back into place,
but not when I slowly bring it back?
