They dont have mechanics anymore..... just parts changers. If changing this part dont work, we'll change that part and you're gonna pay for both of them plus our time.
Course, I dont guess it's the mechanics fault. They didn't build the cars.
Sorry, but I strongly disagree.
I owned a repair shop over 38 years and began working on vehicles when the only emissions system consisted of a pcv valve, and continued up until the computerized systems we have today. Changing parts haphazardly will only cause trouble for anyone in the business, incurring excessive expenses for the repair shop owner and the customer. Repairs are expensive enough, good mechanics almost never guess.
BTW, my customers were under the false assumption that we just had to plug our computer analyzer into the adlc or obd connector and immediately diagnose and repair the problem. This could not be further from the truth. The "scanners" just put us at the starting gate as to the area where the problem exists. It takes a fairly knowledgeable technician to pinpoint the exact problem and what parts, if any, need to be changed.
