I just saw this thread. For what it’s worth, I’ve been fighting the P1341 CEL code for nearly a year. No luck. Am told bank one is off 6 degrees. Yet the car runs perfectly. Surprisingly (to me), it has passed CA smog test twice in the last year. I have the CEL cleared at a Porsche shop and they take it to the smog station. Evidently the test itself does not create the conditions to throw the CEL. But both times, within 30mins of picking up the car at the shop, the 1341 CEL comes back. I’ve decided to just live with it. I know it has little resale value now so I will just drive it until something breaks that I don’t want to pay to fix. Kind of liberating actually. I don’t worry about the car as I had with my old 911’s. And I hate to admit it, but the 986 is actually more fun to drive than my 70’s 911 cars. Good luck with your car. I’ll be watching for updates.
Below is the 1341 thread, which you’ve probably seen.
