Thanks Peter,
Your evaluation sure makes sense - now, if I can find the Idle Control
Valve ;-) Hopefully the pages I printed from the WSM will lead me to it.
Thanks!!

Clean the idle control valve and verify that you have no vacuum leaks
-- this behavior is a almost always a result of the valve closing too
much on coast due to a vac leak, then sticking shut as the engine speed
comes down from the dirt.
I doubt anything would show up on the diagnostics.
The "device" you need is a LED with the ground provided by the test
socket, I think. You count the flashes. Could be wrong, though, never
used it.
