My engine stalls at idle or when slowing down?

My 2003 Dodge Caravan with 3.3 l V6 Flex stalls out when I run air conditioning on high with recirc on when I come to a stop. It starts right back up but when I put it in gear it stalls out again and I have to keep my foot on the gas to keep it running and get it to go. I have changed the crank and cam position sensors and the stalling problem has gotten better but it still does it so what else could be causing this?

No the check engine light has not come on since I replaced the cam and crank sensors.

My 2003 Dodge Grand Caravan Sport has been giving me intermittent trouble for just over a year. While driving, the engine seems to be surging as though it is not getting enough fuel. The RPMs rev to 4000, especially when going up steep grades. When pulling out of the driveway, or accelerating after stopping at a stop sign, she sometimes stalls. After pulling her into park, she starts again right away. No lights have ever come on on the console, and when I have taken her to the Dodge Dealer and local mechanic nothing has shown up on their diagnostic equipment. No one can seem to decipher the problem. I have had the spark plugs and wires replaced, the transmission fluid changed, the fuel filter changed and have tried using fuel injecter cleaner. Nothing has rectified the problem. The oddity to it all is that she might work fine for weeks at a time, only to have the problem reoccur. I am at my wits end with this vehicle! Any suggestions?

I was just wondering if any one can help me figure out what is wrong with my van. Almost everytime I start it it will die out as soon as I put it in gear. I starts back up immediatly but will sometimes just die out again as soon as it goes in gear. Also it jumps a lot and the rpm's flucuate a lot when I stop at lights or go to slow down to stop at lights the sometimes it will cut out and sometimes not. I have put a computer on it but it is not sending out any codes everytime I take it to the place. If anyone has any suggestions I would love to hear them. Also when I go to stop there is a jerking forward motion to I am not for sure if that is part of the same problem just thought I would give you all the details.

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.

That was it. Pulled out the Idle air valve, and the valve was stuck tight. Cleaned it and it moves freely. Put it back in, and the trouble that 4 mechanics couldn't find is gone!

My van stalls and lurches forward a couple of inches when I put it into gear (drive or reverse) when the engine is cold. When the engine warms up it seems to work and drive fine and I can put it into gear without a problem. Everything else seems pretty normal.

Thanks for the quick reply. I just bought this van a couple of days ago. There is no check engine lights, and I have never even looked at the transmission fluid. The transmission did seem to have a problem downshifting when slowing the vehicle down quickly. (It would take a few seconds to down shift and the vehicle shuttered a little bit) I did not notice the downshifting problem when I bought the van. Thank you :)

I took it to a mechanic and he said it was the torque converter. Thank you for the help.
