I joined this site to watch and learn about the issues I have with my 1st diesel. so far I like what I see. I bought a 2003 6.0 new I now have 81,000 miles on it. I started to have the surging and skipping problems with it. No problems till now.Dealer has reprogramed PCM,TCM,FICM, what ever these are? Problems seemed worse now. Dealer has the truck back to install new system. Can anyone put this in laymans terms (especially the term new system,) Thanks ahead for all replies.
