I've finally had it with the parts changers at the dealerships. For the third time I've taken my truck in for smoke just off idle and all they did was change a fuel control actuator per TSB 14. 04. 05. Do the parts changers have the ability to run diagnostics while driving down the road on lets say a laptop? I think I have a fuel rail pressure regulator that is bad but nobody will listen or think for themselves. After driving on the highway to work 80 mi. when I get off on my exit and get back on the throttle I get a plume of black smoke that would make some guys proud but with less power than stock. At night on accel. I dump out a heavy haze and at W. O. T. the smoke is gray. Any ideas before I drive this thing into a lake.
PS this has been going on since July about 5,000 miles ago, and I don't have time to keep taking this thing in only to be told it's fine per the parts changer/code reader.
