Ok my uncle has a 2004 6.0 f-250, going down the interstate and idleing it runs fine. once you get on the throttle it down shifts and revs to 3 grand and no higher, rolling out black smoke. he is pulling a 8x12 enclosed trailer with a dirtbike and tools in it, not a lot of weight at all. Also in park and when reved again it blows black smoke. He says it sounds like it has an exhaust leak when riding against a wall or big rig. Also when you tap on the cat converter it sounds like it has come apart. Possible Problem there?? Any ideas?
