Engine Stall problems of the 2006 Chevrolet Cobalt

My cars engine has stalled several times today, it idles low when moving from a stopped position like at a stop light and when I give it gas it idles high and then when I stop or slow down it stalls in the middle of traffic almost causing a major accident. I was so scared today. I will not drive it again until I figure out the problem. I am glad me or my son didn't get into a very bad accident. When I purchased the car brand new it did this and I took it to the dealership and they could find nothing wrong with it, but it has never seemed to idle correctly.
