Hey guys, i am new to the diesel garage, i am glad to be apart of it. hopefully someone can help me and a friend of mine. My buddy has 03' duramax, last night we were going back to his house after watching a truck/tractor pull, his truck was running fine when we were driving, but when we come to a stop, it was like it was wanting to die, like it was starving for fuel. It was sitting there lopping bad.. please help! Thanks, Redneck!
