Default 3-2-2 Code, MAF/AMM

Car: 1990 240 B230F AW70

Wagon is showing a 3-2-2 code, which to my knowledge indicates a "bad MAF"
I think the car might also be running lean at the moment.

I've tried 5 different MAFs (3 new, 2 used) all of them have a rough idle (some less than others) and they all throw a 3-2-2 code.

Could it be an electrical wire somewhere else in the system rather than the MAF itself?
