Looking for a good, HONEST mechanic to diagnose the 'check engine' light in my Mustang. Cheap is good, honest is better :) Recommendations? I'm in Deming, so anywhere between Bellingham and Lynden.
OR, does anyone have any information on the plug in, do-it-yourself OBD scanner things? Can I really get it diagnosed for free at a Napa or O'Reilly? Or buy a cheap one?
Thanks in advance!
