Hi, I have been chasing some DTCs and have hit a wall. I had p0019, p0016, and c121c. I have replaced bank 1 exhaust cam phaser, oil control valve, actuator, and position sensor. Dealer replaced chains and tensioners. Now it is running smoother, but I still get P0016 and limp mode for first 15 minutes of running. After engine warms up I can clear codes and it runs fine no codes until it sits and cools back off.
Any guidance is really appreciated
