    First thing clean the maf sensor.. if you have a oil type filter will mess maf up.
    Somewhere your getting more air than fuel. Check all down steam of maf is tight.

    X2......the only other thing would be a vacuum leak downstream from the MAF. Be sure you get MAF cleaner....most auto part stores carry it.
