Number 1 could potentially be knock, but 2 sound like transmission. Either way, quit being a Scrooge and put 93 in her!

It does make that ping noise costing though ?( in gear ). And 6th at 45 is just a way to produce it noticeably not my driving preference? Also Florida = no hills. Was referring to a gentle incline.It should not ping coasting, and you should probably not be in 6th at 45 going uphill.
Technically, it's not really detonation, it's deflagration, but no one uses the right term.It is not pre-ignition, but you probably meant detonation.
(Yes there is a difference.)

Driving in 6th and putting in low octane fuel is probably indicative.
Sorry for miss understanding. but is that not a contradiction? If the ECU has learned how to burn the lower octane would pulling the battery not undo that?Try disconnecting the battery. Hopefully the ecu will teach it to burn the lower octane until it is gone.
:facepalmI guess ill just keep pouring in 93 then. Its 3/4 full right now. I guess any amount of 93 has to bring up the octane some. My biggest concern is not that I put 87 octane in, it's that I drove it hard before I knew it was an issue. Though once I heard the strange sound I stopped.
