Is it KNOCKING (like a wrist pin knock) or is it pinging (detonating from too low octane fuel)...there's a big difference.

Exactly what I was asking. Seems likely that he means detonation.

And just to clarify so we are all on the same page if you have a limited supply of fuel you have a lean condition which causes detonation not knocking...
