rough running 7.3

my friend is not very good on a computer so i thought id help him out. he has a 2000 f250 with a 7.3 he says the truck has a delayed start, messed up idle, no high end power, has a hard time getting past 90 mph, not making full boost and sometimes dies randomly coming to a stop. the truck has no codes or engine light. the truck has about 150,000 miles. has a secondary oil filter he changes the oil and oil and fuel filters every 10,000 miles. truck has been doing it for more than a few tanks of fuel and even a new fuel filter and oil change if that could also be a variable. if anyone has any input about this situation it would be much appreciated. im thinking injectors or hpop??? possibly

First thing I would Try is the CPS (Cam Position Sensor).
Good Idea to have a Spare anyway.
Mine woud Randomly Die but Start back up.
Changed Sensor and all was well.
Ford Later had a Recall on the Sensor.

As far as the 90mph I know that mine has a Speed limiter at 92mph. Don't ask me how I know my truck tops out at 92. If you have a Chip or Tuner usually there is an Option of raising the Speed Limiter. I use a Supertuner that will let me but I never raised the Speed limiter Setting.

Those who do not know History are Doomed to repeat it.
Learn from other peoples Mistakes, You do not live long enough to make them all yourself.
