Sounds like you have a vacuum leak somewhere. Check gnttype.org in the resource section for the correct procedure on setting the cam sensor. Check everything on the motor for the vacuum leak,even a small one can cause big problems.

vac leak

I second the vac leak idea. I have personally worked on two cars that would not even run the vac leak was so bad. I checked for the leaks with starting fluid. I just sprayed the fluid around and when the idle picks up the leak is in tha area. Check around the metal egr tube and the joints where the turbo connects to the throttle body. Also check the turbo to intake adapter and all the metal vac lines for cracks.
