You don't say what model car you have but in the case of a 750 yes your processes are correct. If you unplug the MAF while the engine is running it will cause the engine to go into Limp mode and run on the opposite bank of cylinders. Hot wire MAF's upon turning off ignition raises the wire temp high enough to burn off any deposits 1000C, hence the momentary red/orage glow. If you suspect a bad MAF, just switch them side to side and see if the problem moves to the other bank.

Email me a fax number and your car model and I can send further information.

Please correct me if I'm wrong
I would remove the Air filter assembly, look into the mass air flow meter, have someone turn the ignition off and see the sensor glow.does that mean it's working fine or is there another test? like if I unplugged it, should the car stop? please give me details, and I am grateful
Jean
