Hi, Looking for help/info. In November my truck went into limp mode, engine light came up on the dash board, smoke coming out of the exhaust. As it was one month away from a routine fuel filter change; i changed out the filter, fixed or so i thought. However; today and only 150 miles later i have the same problem! I can drive for ten miles or so and all is well after which it drops into limp mode with smoke! Park up, over night, drive off same problem after ten miles or so. An ideas?
