sr20 maf- need info.

[s13_chris]

well sometime today my maf decided to f*** up someway somehow. I havn't done anything to it recently that would mess with it at all.

I have switched MAFs with a known working one.I rechecked all connections by the ECU.I cleaned my maf and light tested the maf plug.one of the pins inside the plug does show power but the other 2 do not. my codes are 55 but sometimes code 12 (when its unplugged) and i got a knock sensor, code 34, a couple times. But it goes away when i turn the key on/off.

i dont know waht to check anymore. contemplating getting z32 maf but will it solve the problem?

Have you gone through and checked all your wiring?
