1998 Dodge Caravan stalls at idle

I own a 1998 dodge caravan and over the summer the wife put the AC on and the car would stall for about 4 days after! Then this problem went away for a while. We stopped using the AC and it still stalls at idle! It also jerks not a severe jerk but sorts of stumbles a little when it goes steady between 40 and 50 mph. I then would spray some carburettor cleaner in the throttle body housing and it would run fine for about 3 weeks. So I took it apart and really cleaned it well even where the air flow motor goes in the housing. It lasted about 3 days and started stalling again at idle. I took it to The Dodge dealership and they said it was the throttle position sensor and 2 oxygen sensors, and fuel filter so I had them changed and it lasted for about4 days and tonight at a stop light the van stalled. Also I want to add that when it stalls it starts rite back up Where do I go from here? Thanks
