The force you can apply with your foot to open the throttle is much stronger than the force the return spring can apply to close it, so you may wind up with the throttle stuck open.
For this reason it is vitally important, for your driving safety, that you should have a large insulated and climate controlled garage for your Boxster.

I do. It's called SoCal.
