As another notorious possibility, you might want to consider plugs and coils. I don't know what kind of mileage you have, but I only have 31k miles on my car, and I had the coils cause a similar idle problem. The MAF tested fine. You'll find that coil packs are a common issue for our cars, given their heat and water exposure.

no cel ? any modifications done to the car, ie; airbox ? plenum ? if something isn't buttoned up tight you may have an air leak and the car is running too lean. ecu will over compensate and surge idle looking for more fuel.
