P0101 and lean condition

[47_MasoN_47]

Ok I checked the MAF readings. I'm not sure what I'm looking for, but at idle it was hovering around 3. Giving it a little throttle to get it up to 2k RPM it would get up around 4 or so. I'm not really sure what I'm looking for there.

While I was letting it idle, it was stumbling around all over the place. I have pending errors for misfires on all banks.

Those values sound OK for non load running. So, the ECM is seeing the MAF data correctly.

Does it act the same with the blitz turned off?

Also, check the throttle position data via torque.
