My '86 is suffering from an erratic cold idle.  Shortly after starting the
van the idle begins to alternately falter then stabilize repeatedly often
stalling unless I intervene with the accelerator. This will continue until I
get out on the road.  On several occasions it has continued even after
getting on the road and I have been unable to accelerate until I pull over
and shut the van off then restart it.

I know there has been some discussion in the past of the idle stabilizer
control unit but I could not find it in the archives.... other than the most
recent instruction to replace one of the internal components.  My
recollection is that there was a procedure for testing the unit.  Can anyone
help?

I do know that my idle stabilizer valve is humming as it should... so that is
working.

What does one of these cost new?  Bus Depot, VanAgain?
