Don't bother- JP is foaming at the mouth to find anything wrong with
what I write. Yes, "ping" and "knock" seem to have become synonymous
at some point, but I remember as a lad (in the distant past - maybe
before Karl Benz named a car after his daughter) that pinging referred
to pre-ignition, and that it had a different sound from knocking.
But hey, if JP wants to score his little victory, who am I to deny it?
If ping now equals knock, or even if it always has, and my automotive
mentor was wrong, then I'll chalk it up to something learned. And it's
a good day when you learn something new.
