My car was running fine for the last 9 months it has beeen KA-T.
I'm pretty sure this doesnt have to do with anything inside.
We'll see.

Anyways.
So I was driving and I took a turn pretty hard and I could here my tire rubbing..
[It pretty much always happens on hard turns, including freeway on ramps]

then as i got on the freeway, I felt a loss in power, saw the check engine light turn on, and it started bogging.

It won't rev past 3k-ish.
I can already tell from the symptoms that its related to the MAF sensor.

I was thinking it rubbed thru my harness but i havent seen any break in the wire after inspecting under the wheel well.

Does anyone know the wiring route of the stock KA maf?
If anyone has any ideas, please feel free to speak your mind and help the best you can.

I NEED TO GET MY CAR RUNNING ASAP.

you need to look at the fsm, and it will matter on your ecu pinout whether your s14 is a 95 or 96 as the ecu plug will either be blue 2 row, or white 3 row.

to make a long story short. the 3 wires going to the maf

*black = ecu ground (DO NOT GROUND TO CHASSIS, it has a pin on the ecu right next to the white maf signal wire)

*white = maf signal to ecu

*black/white stripe = ignition 12volt power supply

I'm not sure if this is the info you're looking for. if not, please be more descriptive.
