Subject: Idle Stabilizer Valve - Later UPDATE: problem *NOT* solved!

Dave,
Join the club! I have the same problem and have done the same
things. So does Larry Himli in MN, and a few other people. I'd
link you to my posts in the archives but I'm kinda busy just at
the moment.
My solution for the time being is to unplug the
idle air bypass solenoid. It idles a bit low when cold but
no big deal. Wintertime is an issue, but in my case I don't
drive the van in the winter... So I'm OK for the time being.

Well, Pablo, things didn't quite turn out like I thought. While my test drive
yesterday was picture-perfect, when I drove the van this morning it was
behaving just as it had been before the swap of Idle Control Module. Problem
not solved, or somehow my van has killed the ICM that I swapped in.
If I unplug the Idle Stabilizer Valve, the idle drops to where it should be. The
ISV is the small tube on top of my 2.1 air distribution box, directly behind the
throttle body assembly and connected to it by a curved hose. It has a short hose
underneath that connects to the crankcase, and a 2-wire connector on the
lefthand side. The Idle Control Module is a small box (looks like a large
relay) that is mounted in front of the right rear taillight. Remove the
taillight to gain access. The ICM is plugged into a multi-lead connector with a
fairly large bundle of wires (~10) coming off of it.
At this point I don't know if the spare I had was bad and just worked yesterday
afternoon to toy with me, whether some wiring anomaly caused it to go bad
between last night and this morning, or whether it was never the culprit after
all. This is damned frustrating! I plan on unplugging the ISV and driving that
way until I resolve this, unless I end up constantly stalling out.
I hope you don't mind, but I am posting this to the list to see if anyone has
any additional input. I will certainly keep you and the list informed of any
progress I make.
Cheers!
