Tim,

Definitely NOT an idle-stabilizer issue IMO.  As a test, just unplug  
the idle stabilizer and try driving the car.  I bet  it'll stall real  
quick.  I'm thinking (maybe wrongly so) that maybe the idle switch/ 
contact is not being hit with the car at idle?  Did you check  
continuity?  I would have though air leak, but then it would be the  
reverse -- faster idle than normal.

Valve issue? Which valve?  You're not thinking any of those 32  
valves, are you?

Ingo
