Can anyone comment on normal MAF air flow rate at idle, especially for 3rd gen (2007-2011) CR-V? Also please mention if you live at high elevation as that would change the expected value.

I'm seeing 1.6-2.1 g/s at 650 rpm near sea level. Suspect this may be too low and a sign of a bad sensor, which would help explain some other issues I'm having.

 

Roughly the same g/s as the displacement. A 2.0 liter would be roughly 2.0 g/s at idle. I would say you are roughly in the ballpark.
