    yo this could be a bad mas air flow sensor or a vacuum leak down past the sensor.try cleaning your maf sensor and check your hoses for any leaks.
    also check the fuel filter and make sure its clean

    i heard it could also be the o2 sensor.. i remember i saw the upstream one and it was bad. and i think my fuel filter needs to be changed also. ima check for any leaks today but i dont think i have any vacuum leaks.
