I traded my 99 f-250 7.3 diesel in for a 2007 f250 6.0. According to my cousin that work in the oil fields, I made a big mistake. The 7.3 is much sought after and I could have gotten more money out of it. Too late. The 2007 had 54k miles on it and the first morning, the cold start was terrible. It sounded like a diesel tracktor, smoking and after 5 minutes of warming up, engine will not run smooth for the first mile or two. It has been at the local ford dealer for a few days to correct this problem. Other f250 6.0 owners talk about "flash" and other remedies to correct this problem, however, I have the slightest of what they are they are talking about. Can someone educate me? Ly of el paso, tx

They are most likely talking about a Re-flash of the powertrain control module (updated program). To do this you would most likely need to go to the dealer.

Don't have power on my obd2 please help me
