I haven't noticed cold start problems with the idle stabilizer
disconnected yet (and its been cold).

And, that makes me wonder about your terminology.  When you say valve, I
think of a mechanical valve opening and closing - like the auxilary air
valve -- it opens and closes to let more or less air in the engine.  But,
when I say idle stabilizer, I'm thinking of the little green box on the
left side of my van with two funny shaped plugs that I can connect
together.

So bypassing idle stabilizer cuts off the signal from the TempII sensor as
well?  Interesting, and that would explain the difficult cold starts.

I think its $25-30 on my van, not too bad to replace.

Thanks for the reply
