2004 Dodge Durango Durango runs rough in the rain

I have a 2004 Dodge Durango. When it is raining, and I come to a stop, it starts to "sputter" a bit & idle funny, It seems like the engine is going to die. If it is raining really hard and I go through large puddles and then come to a stop, the car actually does this quick back and forth jerking motion. I have had a few pretty knowlegeable people try to figure this out and couldn't. Any idea what the problem could be?
