    Flow rates for OEM MAF sensor data; values at idle, cruise, WOT. Criteria based on a fully stock motor (tech pub), N/A w/ aftermarket intake (observed), and S/C w/ custom intake (observed).

    Allow the engine to idle until the COOLANT TEMP
    reaches 75°C (167°F) or more.
    (e) Read the MAF with the engine in an idling condition and
    at an engine speed of 2,500 rpm.
    Standard:
    MAF while engine idling:
    Between 0.54 gm/s and 4.33 gm/s (shift position:
    N; A/C: OFF)
    MAF at engine speed of 2,500 rpm:
    Between 0.58 gm/s and 4.67 gm/s (shift position:
    N; A/C: OFF)
