I have the same issue as you. I have a 2014 SS M6 that throws both codes intermittently. It started when I installed the air scoop. The CAI has been on for years no issues. Is the scoop really causing these issues? I’ve replaced the 02s and my mechanic even relearned the fuel maps and check engine light came on showing -6 LTFT and the freeze frame data is showing +29 STFT. I’m at a loss been chasing this issue for over a year
