Do you ...

have a scan tool? that can get you going in the right direction. A quick way to check for a vacuum leak would be to spray some carb cleaner around the area you hear the leak. If present, the engine should stumble. Also your maf or maf hose can create a problem for you. If the maf is going bad, it will stall at odd times and if the hose has a hole in it, it will cause unmetered air to enter.
