I am back again for help.
Recently my truck has been starting to run rough and puff smoke when it would get around 170 degrees and then throw 2 codes, p1214 and p0216. The most recent time this happened it's was worse it didn't clear up after I turned it off, it would kinda start for a split...
My 97 6.5td has a problem where I would be driving and all of a sudden it will start running rough and blow white smoke and when I turn it off and start it again it would be running find. Also my fuel gauge is jumpy.
