Help, crazy knock sensor reading, low 02 sensors
So my cars been throwing codes p2a00 p2a03, for upstream sensors, got those replaced as well as switched out cats for test pipe, its a nismo 2012 370z, with a tomei catback and Y pipe. Finally got around to scanning it, and its was throwing a crazy knock, in the thousands, and 02 sensors read low, and sometimes not at all lol, but car runs fine so, im thinking it might be a connection/wiring. Let me know what you guys think anything helps.
