2004.5 3500 has a sometimes rough start and excelerating. Check engine light comes on. Had it at the service place and they changed the crank sensor and it ran great for 3 weeks and now back to the same thing. One battery was bad so replaced both. Again ran great for about 3 weeks and again same problem. I have 220000 miles on it and get 20mpg hauling a ton of weight around all day. It will have a rough start and then the sputter problem. Turn the key off and on a few times and then goes away. Any help would be great.
