I fill it with 91 or 94 gas. Recently check engine light came on, got P0328 Knock sensor with a ODBII reader and 2E68 - Knocksensor and 2DED - Power Management from reading with INPA. Knock sensor has been recently replaced so I know it's not the sensor, Engine knock is audible. When listened to with a stethescope it sounds like it's coming from near the top rather than the bottom of the engine. Any thoughts on what could be causing this?
