Bingo! That's what it was!

I bought a new sensor at NAPA after Advance Auto didn't have
one, even though their website said "in stock". Lesson-call and
have a human confirm it.

Anyhow, two Saturdays ago I installed the new sensor. The change
was immediate and obvious. It seems to be taking the ECM a while
to adjust to the new regime.

The engine now starts in 5 seconds or less, even at 12F, and
idles and runs smoother and consistently. I'm hopeful that this
will also fix the "hot engine stall-on-start" problem I mentioned
in my first post.

I've filled the tank up just after the repair, it worked out to
just under 20 MPG. I'm probably taking an extended jaunt
tomorrow, and I'll fill it up and see what the average comes out to.

If anyone reading this needs to replace the sensor, the tool of
choice seems to be a 12 point spark plug socket, but I don't
remember 3/8" or 11/16". There really isn't much clearance to get
a wrench on it; the socket worked like a charm. I had the new one
ready to go so I removed the old one by hand and plopped the new
one in it's place quickly. I didn't bother to drain the coolant.

Don't mind me while I stand in front and brush my shoulders off:)
