John, something else  will cause that problem more so than the idle stabilizer
valve.

There is a big black molded rubber piece with about a 90 degree angle molded
into it. It is part of the air induction system to the engijne. It is located on
top of the engine and forward toward the front of the van near the edged of the
hatch opening in the engine compartment. Remove this and give it a good
inspection. Will almost bet it is cracked and leaking air into the induction
system. If so, replacing it will almost certainly solve your problem. BE aware
though, that it is about a $90 part.
