Need help with turbo problem

Sounds like you've had a duct slip off or split. Look over all the plumbing, and also see if anything around the turbo is hanging loose; something might have popped off.

I've never heard of one of those going bad either, you need to do some diagnosis, don't just start replacing parts. Remove the intake duct and try to spin the turbine by hand, it should turn smoothly without binding. Some play is normal but it shouldn't be excessive. Check all the hoses for holes, though that usually causes black smoke and stumbling. Also are you sure there's no boost or did the boost guage just come unplugged? That should be easy to tell since the engine would feel substantially less powerful with no boost.

James,I am getting boost or at least the gague is reading it. But the engine certerainly does not seem to be getting it. I have done what I thought was a pretty good job of checking all of the plumbing, but you can always miss something. I have not turned the Turbo by hand yet. So that is something I need to do.

The thing about seeing the boost but not getting it is what has me perplexed. Steve

I agree... sounds like the waste gate could be the problem. When it's locked open, it would simply run the engine without turbo boost... compensating fuel delivery to match... no?

My best (and mostly theoretical) guess.
