Previously, the CEL was only being caused by P000D. Now, is P000B is showing up as well. I haven't been able to take the car back to the dealership because every chance I have to take it in, the light turns off
Based on the work they did last time, I want to say that one of the cam actuators was bad and caused something in the engine on that side to break. So when they swapped the L+R to the opposite side, the actuator slowly broke the same thing internally, on the other side... possibly... But I also think it might just be some kind of oil blockage/contamination in that area or timing issue since the light goes away at times.
