Can someone please tell me what's going on????

I was driving and my car was acting completely normal. I didn't hear any pinging like detonation, but my FBK and FKL kept spiking I think it got as high as 12 for my feedback knock. I did take a data log, but I don't think I captured it all. A couple weeks ago I had a check engine light saying my throttle body position sensor and throttle pedal position sensor voltage was off and it disabled my throttle pedal. I also noticed I have feedback on my stereo when I pull my hand brake. I'm thinking maybe there is a ground that's off?? I had my knock sensor replaced with a new one, so I don't think there's anything wrong with that. My car is a 05 Subaru Legacy GT Limited AT Running a Cobb Access port Stage 0 (Simulated Stock) with no modifications done to the car. It has around 127k miles.
