    Sounds like...

    I would start by checking the wiring harness near the MAF sensor. Maybe try to clean the sensor with a type of cleaner designed for that purpose.

    If the code still shows (probably will), replace the MAF sensor itself, one of the filament wires in the sensor may be actually broken.

    Do you use a K&N air filter? Check for oil build up on the sensor filaments as well.
