are you hearing any knocking or rattling at all? could be something is hitting somewhere or something isnt bolted up all the way. might want to post a log in the engine management and tuning section too.

If you are looking at the knock counter per cylinder on the AP then stop then you are just worrying yourself for nothing. Fine Knock Learn and Feedback Knock are where you should be concerned.
