It is possible there is an intake leak and it might be at the boot from the intake manifold to the air mass sensor. Inspect the small hose that has several bellows in it that serves the idle air control motor that is just to the side of the intake manifold. The part# is 13-54-1-437-191. Let me know if this fixes the problem or if I can help you out with further diagnostics.
