I'm happy to see the ICM cured your stalling issue.
Your car has the 3-solenoid electronic EGR valve common to many GM V-6's in the early/mid-90's. These solenoids can fail/stick independently of one another causing all sorts of kooky behavior, including a code 32 (Jeffcoslacker, your definiton was correct for a code 32 on this vehicle) to pop up shortly after start-up and then go off again.
