1988 F250 460 2wd Power Problems
I just bought this 64k miles F250 for use with a slide in camper. I found that on the flat it would run fine but put a hill in the way and It runs out of steam in O/D. Change down and it's OK but get the hill any steeper and it runs out of ooomph again. I get that "pinking" clattering sound when applying the power above about 2k rpm in either O/D or 4th, it probably will do the same in all the other gears as well but I haven't checked that.
If I push things when it's pinking there is power there but it can't be good for it.
I also noticed a metallic rattle when accelerating in all gears at around 1200rpm, This is like it whether the camper is on or not. I thought it might have been the heat sheilds on the exhaust as they were held tight with hose clamps but someone suggested it might be a Catalytic module falling apart and the 2 problems are related.
