Re: My 04 f 350 6.0 is smokeing (black) more than it did...
Take this thing to a shop where they can run a diagnosis on it. You probably have a bad EGR valve and possibly a stopped up EGR cooler.These were common problems on these vehicles causing black sooty smoke and the check engine lamp to come on.
