Engine Performance problem
2004 Ford F250 V8 Two Wheel Drive Automatic 118000 miles
my 6.0 diesel runs fine until you accelerate hard whether you are taking off from a stop or cruising and accelerate to pass or speed up. Then it loses power and acts like it is not geting fuel and blows black smoke and eventually takes on off. If you just let off and ease into it it runs fine. It will run fast as long as you don't accelerate hard. Could it be a restricted air filter or is it more serious than that?Thanks for the help.
