6.0 losing power fast, and a whole lot of gray smoke!
My uncle called me tonight with a problem with his comapany '05 6.0. He said the last two days it has been getting really sluggish and really smoking gray smoke! He had it completely serviced including fuel filters, with no change. He also said the fuel economy has dropped way down too. Could the turbo be going out?? I had some EGR issues with an '04 that resulted in low power and poor milage but I did not have excessive smoke. I told him about the org, so I would not be surprised if he joins tonight, he may even post this same senario for some feed back. Any ideas would be greatly appreciated!
