Easy starting test:

According to the Porsche CIS troubleshooter, you can check quickly for a serious air leak by screwing the idle screw to cut off the air (idle should decrease as you turn the screw clockwise). If this causes the engine to die, then your air leak is not serious, if it still runs you have a "serious" enough leak to correct.

My car stalls/dies when the idle screw closes off the air flow.
