I would assume that the car is not getting enough gas to the engine when at idle. Is it try to cut-off when at a stop. Check the fuel fliter, maybe put better gas into the car (mid-grade) or better.
hi does the car only do it in drive if you put it into another gear does it keep doing it? Also does it do it when the headlights are on?
