Default struggles and dies unless maf is unplugged

If the maf is plugged up the car will struggle at low idle for a bit then eventually die. If it is unplugged, the car runs fine.

Voltage is fine on yellow and red wires.

Where does the maf ground at?

Is it just time for a new one?



P.s. what are the two wires that go down the drivers side with the m6 harness?
One is black, the other Brown.

Finally got around to trying out a maf that I know is working, and I'm having the same problem.
12± at the red wire
5± at the yellow wire
The ground is on the driver's side rear head, correct?
p.s. What is the dark brown wire that runs with the ground?
