I guess what I was getting at was how do you really diagnose problems? We all know that most modern "mechanics" (and I use that term loosely) get a readout from the computer, and start changing parts in the area the computer pinpointed until the problem goes away. Very few seem to know how to use a multimeter or stethoscope anymore. Very few seem to understand that just because the apparent problem has been resolved, there may be a root cause hidden a level deeper or the system just upstream may be the real culprit...
