Hi
what is the correct spec for MAF reading at idle?
i am getting 6.8 gram per minute at idle when starting cold.

Follow up:
I just measured the MAF value after warmed up at idle. It reports 4 grams per second vs. 6 when cold started.
I looked everywhere and couldn't find the spec value. I am just trying to get to the bottom of P050B which I thought was resolved when I cleaned up the throttle body. The car didnt throw the DTC for a few days but now came back. Based on the Toyota official troubleshooting it recommends replacing the MAF before troubleshooting further as long as STFT + LT <20. Any expert out there? Thanks in advance.
