   I was traveling on a 55mph road. My Chevy Silverado started to shake and lose propulsion. I pulled off on the side of the road. In idle it shook. The dealership was one mile to my south. I turned on the hazard lights and went to the dealership. I could only get the vehicle to 45mph as in shook very bad the whole way. It felt as if the engine was going to explode the whole way there. The vehicle was taken to the dealership where it has been initially diagnosed as a bad lifter.
