I just bought an 03' f250 super duty with the 6.0 powerstroke. It has roughly 104,000 miles ( 90,000 when I bought it). I just had the #5 injector replaced, the transmission completely serviced, and a temp. sensor in the tranny replaced. It ran good for about a week,and it starts fine, but stilll has white smoke out the exhaust, and black whenever it is under any accelleration. When I am just cruising at any speed, it really seems to be misfiring ( more noticeable on the highway). I have to give it some gas for the hesitating feel to go away, and then it smokes out the exhaust , usually black. I really love the truck, I am hoping that someday it will run like it is supposed to, so I can really enjoy it.

Also, it has absolutely NO power after start-up, It does not get power for a good 15 minutes of driving, even in 95' weather.
