Don't really understand your question or why you are unplugging MAF.

One of the tests for a car that is running badly is to unplug the MAF. If the car runs better with the MAF unplugged, the MAF has probably failed. If no change, the MAF is probably OK. If the car is running OK with no Check Engine Light, there is no reason to unplug the MAF. As a matter of fact, unplugging the MAF will probably set the CEL.

I had a MAF fail last Summer with no running problems, just a CEL with O2 sensor mixture codes. Observed MAF values with engine running & they were out of spec. Replaced MAF & mixture codes fixed.
