I think that is just a harmless MAF plausibility fault. Could try adjusting the MAF around a bit with washers or one side or the other to change the angle and see if that helps.

I wouldn't run this code for long...Had it on a previous car, and although it did not affect performance, it played with fuel trims and lean conditions at the end.
Keep an eye on the LTFT and try to fix it.
