There is no such thing as a code that says the MAF sensor is bad. The code indicates that the MAF sensor is giving an incorrect reading for the conditions, but does not mean that the sensor is bad. There are a bunch of things that can cause the MAF sensor to read incorrectly, the only way to find out what is doing it is to have a good scanner such as the SnapOn MT2500 that allows you to look at all the inputs and outputs that the sensor sees, while driving the vehicle. As much as it goes against the hot rod way of doing things, I think you will be ahead of the game, moeny wise, by having a shop with the proper equipment diagnose and repair the problem. You can throw parts at it until you are broke and still not fix it.
Hope this helps,
