In my case it was the idle stabilizer valve. I found that by resetting
the engine idle ( engine warm, ISV disconnected) and cleaning up the
connections, the problem went away. However, the Idle Stabilizer
control, that electronic box behind the righthand brake light, may have
to be removed and re-installed. if that doesn't do it, further sleuting
must be accomplished.
