FI or ISV?

[bludodger at att.net]

Hey Listers--

Just a preliminary question or two about a problem I
have been having.

Seems that there is a problem with my car upon starting,
where the car will not hold idle @ 800-1000 RPM.
Instead, it will linger around 650 or less. When I step
on the accelerator it will rev and drive fine. However,
at the next stop, when clutched, the car will return to
the poor idle or even stall. This problem does not
always happen (but its happening more and more---as in 1
every 2 starts or so)and is NOT weather or temperature
related (as far as I can tell). I have noticed that when
the problem occurs, if I turn the ignition off and then
restart, the car will idle correctly (almost as if
it "resets" itself). Also in Stop and Go traffic the car
will develop this problem even if originally(at the
start of the trip) it was idling properly.

I have replaced the ISV with a used one and there seems
to be no major change in performance. Any other ideas?
What else should I consider? FUel injection? yikes I
hope not.

Thanks in advance for all your valuable help
