Praying it is a defective camshaft solenoid/actuator.

crap... that sounds... not good. Sounds more serious than a spun camshaft. Flatbed that baby to the dealer. I never had a misfire in my car with the spun camshaft.

It's not. Congrats, you won the lottery too Did the misfiring start to clear up as your rpm went up to around 3k or so? That's what mine did. Yours sounds like not only sleeve spin but probably even cam gear slip as well. Had that one too. Make sure you replace the actual cam gear on the affected side unless you want the engine out more than once. The intake cam gear is another ~600 or so.

For some reason in certain instances when the sleeve spins it manages to damage the actuator in the cam gear. It gets stuck and this overcomes the friction disc connection to the intake cam. The cam then actually spins relative to the cam gear to the point that you get massive misfiring on all the cylinders on that bank at idle. If you rev it up enough, it's not advanced that much for the higher rpm and the misfiring resolves.

Default Update on possible spun camshaft

Just installed new camshaft acutator. Don't want to speak to soon but she is running better than ever! All codes cleared and no misfires. Not sure if I should change the actuator on bank 2 as a preventative measure?? Anyways, thanks for the feedback guys, and will keep you posted. Keep them fingers crossed.
Now just waiting on new tune from Kevin!

So all you did was change the actual solenoid? The actuator is built into the cam gear. If so and that's actually the fix, congrats! You somehow dodged a big bullet.

Yes just the solenoid on top of Bank 1(part 22 in pic). So far so good. Have only logged on 20-30 miles so far. Not sure if related but 2 months prior, I was throwing an intermittent CEL which was:
P1372 Valve lift control, above limit value
Had 2 different Porsche techs look at also but they couldn't figure out why. Then the misfires and now all seems to be good. Almost too good! Think need to shop for a Fidelity Platinum ext. warranty now.....just in case!

I would be cautiously optimistic but looks like you may have escaped a very large repaid bill. Congrats
