Chrysler Pt Cruiser possessed, please help

Dump this shop. Go to a real shop. It is obvious that the mechanics are not taking a moment to think THROUGH the problem, or else have no idea how the systems in the car are laid out. A good mechanic LISTENS to the customer. The customer will tell the mechanic what the problem is - sometimes prodded by the right questions. A good mechanic never assumes that a solution to a problem is the same solution that appeared to work on the last several problems. A good mechanic will take what the customer told him, use his own knowledge of the car, the systems and mechanics, and then THINK his way toward a solution. Usually, a good mechanic can think his way to a solution faster and cheaper than all that high priced equipme that was not designed to be an alabaster short-cut.
