Don't waste your money on the CRC stuff or add premature wear by "cleaning" it. The MAF is self cleaning by heating to burn off any residue, but if your MAF is going bad, you're only putting off the inevitable. An easy way to test the MAF is to unplug it and see if it affects how it drives in a positive way. Clear your codes, see if it comes back and check the other forums I suggested.
