My 2003 Dodge Grand Caravan with 3.3 engine stalls when first started unless you hold the gas pedal part way down and wait about 1 minute. It will also do this, and /or hesitate on initial accelleration when restarting after it has been parked a while. It all clears up after a minute, and the car runs great at rpms above idle. The engine does occasionally seem to misfire (sounds like it is going to stall) when idling at a traffic light with a warm engine. There are no codes, and I have had it to 3 mechanics including the dealer, and they can't figure it out. The upstream O2 sensor, and MAT and fuel pump and filter have been replaced. Fuel system cleaner seems to cause a small improvement and the 3M fuel system cleaner kit also seemed to help for a while.
have the same problem?
