P0430:
P0430 indicates that the main three-way catalytic converter on bank 2 conversion level is too low. Clear the code, then compare the O2 sensor voltages before and after the cat, if the voltage traces are following each other, the cat is toast.

Right, I have found the P1341 info before - hence why I was considering looking at a new solenoid to start. My understanding with the 986.2 is that with Variocam Plus (oil driven, infinitely variable adjustment) faulty actuators aren't the same as with a 986.1 and its DME-driven actuator. With a Plus engine, my understanding is the oil passage would have to be blocked (potentially with either green bits from a solenoid O-Ring or brown bits from chain guides - something I'm looking for next oil change.)
What I am asking though is if the circumstances that caused these initially haven't been repeated, why would they come back? Could a misfire duration of less than 10 minutes from a poorly seated plug cause cat failure? Just seems odd that 2 specific situations that haven't repeated would result in these conditions.
