Hoovie, of Hoovie's Garage fame, when through with with a Superbird he picked up on Bring a Trailer. He chalked it up to bad luck and took it to the car wizard to fix, just making it a part of his program.

The Wizard did a great job but found after getting into it the seller had misrepresented a great deal on the car. He finally had to get BAT to step in and help him get his money back.

This is all up on YouTube so a search of his back programs might turn up some helpful info on your problem.
