I'm found I think two mechanics in Oakland, ca, who are supposed to be very good, and reasonably priced. A David Pham, and James Auto Repair. Now I have to decide who to go to...David Pham quoted $95 to diagnose, and around $550 if he had to tune up and replace the big fuel filter..(don't know the name..sorry), the other shop said they would drive it to see the problem, and they said the labor is around $47 for a half hour so it should be around $50 for a diagnosis...I don't know much about repair except for changing the little filter so i Really want a Good, Honest mechanic....
