Holy crap, if your mechanic doesn't already know this you need to get your car out of there as fast as humanly possible. The guys who work on Porsches know Porsches. Not all "euro" car shops are created equal.

A hole in the bottom of the intake plenum was the issue. I haven't a clue what caused it but they covered it and everything smoothed out.

Glad to see they figured it out, but did they not test for vacuum leaks during initial testing? I feel like that hole should have been fairly easy to spot. Irregular idle is often caused by vacuum issues. Again, I'm just wondering if you should reevaluate your relationship with said shop. Looking out for you and your car in saying so.
