Don't take the parts guys word for anything. Most of them can barely tie their own shoelaces, and most of them drive pos junkers that are held together by baling wire and bubble gum. People freak when I drive the Z to the parts store, get out in my red shirt and step behind the counter. I get all the 'how do I fix my car' questions, to which my response is 'Google is your friend'. They pay me $8 an hour to sell parts, not diagnose your broke down pos. Diagnostics are $100 an hour.....
