The only other thing that comes to mind is, you could always find a friend that has a good working MAF, put it in your car for a while and see how it behaves..
I don't know any Legacy (or newer WRX buddies). I see them around but nobody close. I guess buying a new MAF sensor is in line
I really wish I would have thought of doing a compression test while the plugs were out last weekend... damnit. My knuckles are just starting to heal lmao. I could take the car up to AZP this weekend but I HATE paying for labor for something I could do myself.
