In the mornings when I first start-up and let the engine warm up for about 5 mins, and I take off, the first time I come to a stop sign or any stop, the engine will start bucking causing the whole truck to shake and most of the time the engine will just stall out. And even after I have been driving it for awhile sometimes when I come to a stop the engine will stall randomly, only with a MUCH less buck, sometimes unnoticeable. Anybody have any ideas? Any help will be appreciated
