I recommend disconnecting the battery for a minute or 2 (clears the stored trouble codes and allows the car to "relearn" ). Start the car and let it idle for a few minutes then drive it and check for trouble codes after.
Myself, I got tired of buying the expensive Bosch MAF every couple of years so I've been running a Microtech MAF for more than a few years now - took awhile but it did die and I exchanged it(with the proof of a receipt) with no questions asked. Those Microtechs have a lifetime warranty so if you think there is problem with the actual MAF exchange it for another.
