Here is the statement on the 1286 code. I would not consider this if you are running a lower octane fuel.

"The ECU internally generated pulse was not detected. It isused to verify electrical integrity (shorts or disconnection) ofthe knock control circuitry both internally and externally. Check wiring and Knock Sensors"
