Just let it idle and make sure the line stay steady.
This is what our dear friend JFP in PA posted as reply to my question in the same matter.
Camshaft position deviation. - Pelican Parts Technical BBS
I’m also a new owner, and I’m trying to learn as much as I can from the more experience ones.
It is great to have people like JFP and many others that are willing to take their time and share with us their knowledge.
Good luck and enjoy you boxster, I know I do.
