i just baught a 04 f350 dually, it has only 36,000 miles on it.. i think an old man just used it to haul a RV.. the problem i have is a couple of times it actually acted like it stalled when driving it... no power, no revs, but than black smoke and took off like nothing was wrong... any suggestions,,

Sounds to me like maybe problems with the VGT. I am thinking that your turbo is sticking. Main reason: Your truck has only been driven an average of 5,000 miles a year. That is brutal on these engines. I am betting you will find rust inside your turbo. Is it throwing any codes?

Extremely low mileage on a 6.0l is not a good thing like on a gasser.

NO CODES, ONLY DONE IT TWICE SINCE I BAUGHT IT.. IT ONLY DID IT WHEN I FIRST BAUGHT IT, I PUT ABOUT 1200 MILES ON IT... I HAS SURGED, SEEMS LIKE WHEN IT STARTS SURGING, I CAN TURN THE TRUCK OFF, RESTART IT, AND ITS FINE..... NOT SURE HOW IT SHOULD RUN CUZ IM NEW TO DIESELS, BUT IM SURE IT DIDNT RUN LIKE THIS NEW.... I DONT HAVE ANY OF THE EGR SYMPTOMS, NO WHITE SMOKE, PUKING, BUT IT SEEMS TO ME LIKE THE TURBO DOESNT SPOOL UP LIKE IT SHOULD, BUT SOMETIMES IT RUNS LIKE A RAPED APE.... A FEW TIMES I REALY HAD TO BEAT IT TO GET THE TURBO TO WHINE..... ALL IN ALL IT RUNS GREAT, BUT SOMETIMES IT JUST ISNT RIGHT!
