Went to get new truck today and asked salesman if I could drive it around for 30 min. or so to see if the cel would come on... . and guess what... . it was already on and the truck ran goofy. I will go back on monday and see if they have another one similar that runs right. Also I cannot reveal my source but I spoke with a former dodge service mgr. today and he told me that ALL 6. 7 trucks will eventually have emissions trouble ,excluding c&c models. The o8's seem to be a little better because they turned the fuel down. He also said the egr is the heart of almost all of the problems that are soot related. I am considering keeping mine and spending the money on egr & dpf deletes w/ programmer/s ... ... 7700. 00 will buy a lot of performance . I am very unsure at this point.
