i scanned and got these codes, i replaced my maf 10k miles ago so i dont think it could have gone bad again. and under wot i hear what sounds like air rushing through something

3 Faults Found:
16486 - Mass Air Flow Sensor (G70): Signal too Low
P0102 - 35-00 - -
17521 - Oxygen (Lambda) Sensor: B1 S1: Internal Resistance too High
P1113 - 35-10 - - - Intermittent

seems to me the maf is failing causing you to run rich. Lock block 003 and 31 to see roughly what your afr is. What year is your car?

I can say that the o2 sensors are related to your maf problem. Both sensors wouldn't fail at the same time. I think you are just running very rich with the maf. Unplug it and see what happens.
