I got a CEL this morning on startup. The codes are P1031 and P1026 and these look like the intake manifold runners are opening when they shouldn't or something like that. I am also getting P12544 and P9728.

Anybody have any ideas? I have a good in-house fleet mechanic but he is not a Porsche guy. Looks like off to the dealer if I can't fix.

Thanks, Mike
