Hey Guys,
I started my 997.2 c2 couple of weeks ago and it popped a CEL and the idle was jumping up and down ~100RPM. The code read P2414 02 Sensor Exhaust Error Bank 1 Sensor 1. Thus I assumed a vacuum leak and performed an Evap smoke test and found what I thought was the culprit. found smoke coming out of the crankcase vent hose which was very brittle. I replaced the hose and then cleared the code. The idle was still jumping up and down and more codes came the next day.
I now have codes P2414 02 Sensor Exhaust Error Bank 1 Sensor 1, P2195 02 Sensor Signal Biased / Stuck Lean Bank 1 Sensor 1. P0171 System Too Lean Bank 1.
Does anybody have any ideas what it may be?

Was the car stored for the winter? Check the wiring for those O2 sensors on that side to see if a rodent got to them over the winter.
Porsche wiring is evidently made right next to a cheese factory.

Not necessarily relevant to you, but I've had my 08 for almost 6 months too and DD it all winter. Started rough and blew a code one morning middle of the week. A rodent chewed completely through crankshaft sensor wire. Different code, different issue, but getting under the car and checking all the exposed sensor wires that can affect fuel mixture isn't a bad place to start.
