We have a 2000 Chrysler Town & Country Limited Edition that stalls constantly until warm. We have to let the car warm for a long time before driving - sometimes as long as 45 minutes. The problem went away during the warm summer months, but now that the weather is cooler, the problem has reappeared. Dealer (who is absolutely useless) shrugs their shoulders and says the problem doesn't exist. Any ideas??

I have heard this may be an oxygen sensor. It is something I heard years ago. Could have been on one of those radio call in shows. Anyway they said the oxygen sensor plays a bigger role when the engine is cold. It's just a thought.
