I can't for hell figure out what the hell is wrong with my maf. I replaced it with a used one and its giving me the exact same reading as my old one so i'm guessing it's the harness but I really want to make sure cuz i need to get it smogged asap.

Anyone know of any really good places that knows their electrical stuff? Or any place that specializes in nissans without the dealership prices around the 805(oxnard,camarillo,ventura) area or maybe even around l.a.?

I'm desperate.
