so i had my car running for a week perfect. It is soo fast, before the car idled perfect 900rpm ish. Now the car shakes violently at idle and is very slow. All of a sudden when driving i heard a loud backfire and the power instantly cut off. Can maf's go bad like this? i'm using a z32 maf and safc2 setting are 2in 5 out i'm using a s14 sr20det.

When i unplug the maf the car idles like once before.
when i plug the maf in, car wants to die.

Checked wiring it seems good.
