Have had this problem for a year...turn my ac on and run it for a little while all seems well, till I have to sit and idle for a little while if I shut the car off it won't start back up and if it does start it idles rough whole car shaking spits and sputters then dies.let the car sit for an hour or 2 go out thing fires back up no problems. It only does this when I use the ac. I've replaced coils, spark plugs, fuel pump , and cleaned the egr. Not very mechanically inclined just started learning. Any help on this matter would be amazing!!
