2001 2500hd, 8.1L
The last two times I’ve traveled for work, when I got back and was able to drive my truck, it idles rough and runs rough for the first little bit. When I’m able to get down the road a short distance it smooths out and stays that way. I didn’t think anything about till last week when I traveled again, got back and it did the same thing. Is it really something about sitting for a week or is that a coincidence? Otherwise runs fine. I recently had the fuel pump replaced if you think that could have something to do with it.
