This is a '99 Accord coupe (V6/Auto). The engine makes this whining noise at about 2K RPM - above and below that, it doesn't. I had it given the full inspection when I bought it (used), and it basically would qualify for their certified program because it was in such good shape. Is this just a Honda thing, or is there something not right? Also, what's up with that whining sound Hondas make when going in reverse? What causes that?
