    MAF issue?
    Mine was dead after 3000 revs, replaced MAF and all OK.
    You could try cleaning the MAF, although I doubt it will make any difference. Previous posts explain how to do this.
    Check the connector to the MAF as well, the contacts might need a clean.

    maf = Mass Airflow Meter

    it is located directly after the air filter housing . it fixes onto the filter hosing and has an electrical plug coming out from the side and a large diameter flexible pipe the opposite end .

    basicly the ecu monitors the amount of air flowing in using the maf , and the ecu then adjusts the fuel accordingly
