If it's only idle speed, that's not a problem.  Most people seem never to
have heard of it, so methinks it's something my seller had explained
(improperly) to him, and it just passed itself on.  I don't live anywhere
near California or the west coast, and I know they're stringent in
requirements, so it was hard to judge if it really was a feature or not.

underadjusted idle, which is fine.

Thanks all
