Right on Warren! As a retired Tech for Acura (and other Jap cars), I ran into this from time to time. I refused to do it this way. As Warren said, who pays if the part is bad, but more importantly, the diagnosis is usually wrong. generally it's a WAG, and the customer is ripped when the car's not fixed, therefore, it's gotta be our fault. What really got me was the customers who came in on the hook, and when given the diagnosis, stated "that's not right, the tow truck driver said such and such was bad.." I would just ask why thsy belived this expert diagnositian who was laying on his back in the snow for $5. an hour, and not me who had the training on their car? Of course on the old cars, it's easier to diagnos most problems than it is on today's cars. Arkie Ray Jones Hope to see all y'all in Battle Creek this June.
