"Using the scan tool, check the values displayed for "MASS AIR FLOW RATE." The airflow rate should be 0.20–0.53 lb. per minute (1.5–4.0 grams per second) at idle"

 I checked mine today and its at 0.01 at idle, and 0.02 at 2500 rpm. When driving at WOT it topped at 0.09 or 0.68 g/s. Bad MAF? No codes, but LTFT is at 11.2.
