IMO far to many techs /mechanics dismiss what the customer is telling them. They put it on the computer or diagnostic equipment (not limited to the transportation world) and say there is nothing wrong. The problem here is twofold, one the same sensors are being used that may be causing the problem, to diagnose it and two sometimes the problem will exist only under a given set of criteria (that may not reproduce its' self in the shop or at time of inspection).
Let me tell you about an experience I had. I bought a new car but the car never idled correctly. The dealer said it was normal (no codes). At 50k miles (still no codes) when I changed the spark plugs as I pulled off a plug wire to my surprise the center electrode portion came with it. Guess what, it idles better.
Yes, sometimes it is the customer, In my field I have not found more than a half dozen who have actually read the operators guide and a large percentage of time is spent "educating" the customer. This doesn't make me think gauges need to be stupefied, just more education.
