This weekend and I've notice this before, the wife and I went to Rosenberg, outside of Houston. After being on I-10 for a while (45 min - 2.5 hrs) going 70-75 mph, we stop at a rest stop, convience store, or slow down through a town. In any of these cases, the truck goes down to an idle basically. In all of these cases, my truck runs very rough. The RPM do not change but the truck feels like it has a miss in it.
Here are my questions:
1. Is this normal?
2. Anyone have any idea what it may be?
3. My warranty is about to be up, should I take it to the dealership and have them look at it?
