I am having both of these codes appear and recently had a fuel delivery issue that required me to replace the fuel rail, injectors, and fuel pressure regulator. The codes that are not popping up are said to be directly related to each other and are due to upstream O2 sensor issues. My question is, would the long running fuel delivery issues that I had contribute to damaging the 02 sensors? By the way, after the fuel related issues were resolved, the car is running like a champ!
