    I have seen a post on the site, cant find it and also did a search. some one replaced a sensor and fixed the problem.

    My issue is the same, i have a 01 chevy 3500, with a 6.6 turbo Diesel at idle, truck run rough, (Kind of like a gas engine missing on one cylinder). I have taken to the Dealer several times, there are no codes that show in the computer. they have updated the computer with the current version. it helped for a little bit. but is does it again after a few weeks. i am thinking it could be a MAP sensor. i was trying to find that post so i could re-read it and see if it was close to the problem i am experiancing. Any direction or help would be helpful.
