    I have a 96 F-350 7.3 and my problem is that when ever I'm driving it will just bogg down and pour black smoke out the exhaust. It is a 5 speed and 1 and second gear it runs fine. The check engine light is not on. Appreciate any help take care

    Do those have water separators on them?? Could be a vacuum line is broke or came off somewhere, maybe one to the turbo??
     
  5. Could be the oil is thinned out and the high pressure oil sensor is kicking try changing the oil my 7.3 did that and all it needed was a oil change do you use rotella? good stuff but I got a buddie who is a LE dealer and thats the stuff I use kinda pricey if you dont have a 'buddie' but worth it its red like tranny fluid but who cares it works.

    I have a 96 and I can say this is a very odd problem. I can say it is NOT a CMP sensor or fuel filter issue. The black smoke has me puzzled, I have not had dirty oil cause this on my truck and I change it @ 10.000mi. I guess start with the basics; what mods have been done if any? Any trouble codes in the computer? Whats the ambient air temp? Whats the boost? and are there any exhaust leaks before the turbo? How many miles on the engine? Possibly a bad injector(s). Black smoke is over fueling due to either not enough air (bad turbo, restricted air flow) or bad injector(s).

    try the the fuel heater or cold weather baffle. Is the bogging like an engine brake then it takes off with a clould of black smoke? A 40.00 part

    does it only do it when the outside air temp is below 40?
