[Subanez]

I haven't had the chance to check for leaks (extremely busy this week), but I think its most likely a vacuum seal issue.

The reason I think this lies in the fact that once the engine is fully warmed up, there are no problems at all. The engine runs fine. Its only when the engine is cold that it runs so poorly, leading me to assume that once the engine pieces and vacuum tubes have heated up, the pieces expand and seal any leaks that there might be.

Sounds logical? Now, how much should I be expecting my dear Porsche mechanic to want to charge for testing/verification/solution of this problem?

Ugh.
