Hi Ian I hope this is the correct Ian. I used to be a member of the owner's association and we both worked at Veteran's Affairs. Anyway I sold my Z to my sister and the Z has some power "surging" issues and A/C issues and wondered if you and John still had any diagnostic equipment that might be able to help while she's here for a week or so.
