Low power, bad mileage

I have a 2000 f250 with no chip or any after-market additions. A few weeks ago on a road trip with no load it started sounding sputtery when attempting to pass. I noticed that passing power was very lacking. It was slow getting up to speed, even when it downshifted. I also noticed it sucking down the diesel. The next day, after a very cold night in the woods, it took a while to get it to crank and it blew out a big smoke cloud when it finally did. It wouldn't idle without me hitting the throttle. I had to drive it for a couple of miles before it would idle right.

Since then, I can only get about 200-250 miles out of a tank and its sluggish. I don't seem to hear the turbo all the time either, but I know that it is turning.

Any thoughts?

I still haven't taken it in because I can't stand the thought of taking it to the ford dealership. I guess I'm gonna have to bite the bullet.

if you see a light at the end of the tunnel, it's probably just a photon torpedo

you gotta remember those guys work on these trucks everyday and they have access to all the correct diagnostic tools and also Ford technical hotlines. you'll probably save yourself time and money, not to mention they don't use cheap aftermarket reman parts and they warranty their labor and parts. just my $.02
