My first Boxster, my first problem

[Stender]

OK guys, thanks very much for the answers. I will try to do that. But have you listened to the youtube clip I put up? There is some kind hissing/scchhhhh noise when the engine shuts offl? I have never owned a Porsche before, but it seems kind of strange.

when i had a strange hissing noise i found it was the vacuum hose that connects to the brake booster. Once i popped it back in it was fine. Its in the front trunk lower right had side of the brake booster. I have a 99
