Ive had my manifold and turbo off to drill out a snapped stud, and have put it together again, So i went to put me foot down and it started to boost normal and then it died off and is now jumping about like skippy on speed every time its about to boost at even slow speed. It wont even climb a hill cos as soon as any boost is about to come on it jerks about. All connections are fine Any ideas.

 

Has the actuator come off the waste gate pin?

In which you will be getting no boooooooooost
