Most idle issues are caused by a vaccum leak somewhere in the tubing that surrounds the engine.
From what I understand from experience and from other members, the MAF has nothing to do with idling issues, a bad MAF usually is diagnosed when the car has a lack of power or hesitation at speed.
So, use a can of carb cleaner (or opened, UNLIT propane tank) and spray around the engine compartment paying close attention to the tube routes. When the idle jumps, you've found your leak.
