Your problem is when you put it in drive and hit the accelerator the car hesitates to go Once it gets going it seems to be fine It is just the inital starting out Its also dies when you come to a stop?

vaccum leak

Check your vacuum lines for any hissing. If someone can correct me, There should be a vacuum line routing sticker under the hood. Also check your air hose from the air box to the throttle body. I had this problem on my Sunfire and I needed an intake hose and it was fixed. Good luck.
