    If the mechanic says "I think it could be the..." then they should have a good reason for it. It takes a very good understanding of the system to be able to diagnose these types of problems, which your mechanic doesn't seem to have. Find a Gold Shield Station near you and try having them diagnose the problem. http://maps.google.com/maps?f=q&source=s_q&abauth...
    Don't let this mechanic guess with your money!
