Check your IAC, the IAC allows a little air into the engine when the throttle blade is closed. The PCM meters the air via the IAC valve and the behavior mimics the dashpot on a carbed engine. If the IAC is dirty or faulty then in cannot deliver the correct amount of air when it is suppose to and the engine will die. If all else fails drill a small hole or a few small holes in your throttle blade to help aid in some air flow when the throttle blade is closing, it will trick your computer and not die...
