Oh, no question about that.  They're supposed to be that way.  And
I've always thought it was kind of neat that in theory you could
start at the top of a mountain and arrive at the bottom with a cold engine.

Ask anyone with a Digitool.  Used to be I could tell you the rpm that
the injectors would come back on, but no more.*  On the 2.1l you have
to get above 2500 rpm before anything will happen, and it cuts out
when you reach 1500 rpm - so the automatics don't spend nearly as
much time with the fuel shut off around town as the manuals.

*Ok, 24.33 says that with throttle closed the 1.9l will shut off the
fuel at 1500 rpm and turn it back on again at idle speed.  Which of
course is why it bucks if the switch doesn't open soon enough.
