First that was an intermittent problem. The car stalls when slowing down at street corner or when breaking to park home.I tryed to cleaned throttle body .No difference appears.Last week it it's starts to do it all the time . It stalls in traffic at red lights... The engine was not running well.I change sparks plugs + wires . Notting changes engine stills stalling and running like one cylinder's is missing.
I'm had a similar problem with my Caravan this past October. Ask your mechanic to check the fuel pump and oxygen sensor. There was a recall on Airtex fuel pumps in 24,000 2000 Caravans in 2006, so might want to see if it was one of the affected pumps and it can be replaced for free. Good luck!

Is the fuel supply okay? Has it been cleaned ? Is idle speed set correctly as a matter of interest. Sometimes if the fuel supply is just a little diminished and the enginde is allowed to run more slowly than it should under load , can result in bad behaviour. Agood tune and fuel system clean may do the job. Probably best to get it on an electronic diagnostic system
Purchase "02 Sensor Safe" throttle body cleaner spray;
Drive the vehicle a few miles, bringing it to full operating temperature, then park it in your driveway with the engine still running;
Gain access to the throttle body, and hold your thumb on the butterfly linkage so that you can open the throttle butterfly when the engine begins to load;
Begin by spraying throttle body cleaner spray on all linkages around the throttle body. If the engine begins to bog because it is aspirating throttle body cleaner, quickly open the throttle butterfly to keep the engine running.
Once you have cleaned all around the throttle body, spray cleaner DIRECTLY INTO THE THROTTLE BODY, opening the throttle sufficiently to keep the engine running. It will run rough during this process but try not to let the engine stall.
If the engine stalls, restart it, and continue cleaning the throttle throat until you see clean metal.
Pour some fuel system cleaner into the gas tank and drive the car a little more before parking it. Try to find an excuse to accelerate hard, WIDE OPEN THROTTLE momentarily if safely possible (as when accelerating to merge into traffic on a highway).
I had this problem once,albeit on a different vehicle. Try disconnecting the air filter trunking from the throttle block, see what the inside of the throttle block looks like. If it is all black and oily clean it all out thoroughly with a rag or strong tissue, there is a small by-pass drilling in this body which can get blocked.
My 98 plymouth grand voyager was having same problem changed several sensors before finding a very dirty crankshaft position sensor. After removing and cleaning my problem has disappeared. Youtube has a video on replacing this sensor. Careful when reinstalling. Position is critical to far in and hits flywheel. too far out and will not start.
i would start by cleaning out the throttle body. they collect soot and not have to be a lot either for it to mess up the idle speed, i had trhis on mine soon as i dipped the clutch to slow down the rpm dropped to about 400 to stall, i cleaned throttle body out ( taking air intake off and wipe round inside and the butterfly will be enough) and now it idles and the rpm dont drop below 900
