Update: I installed a NTK upstream o2, got a different maf sensor from a turbo cx-7 (looked to be in better condition than mine) and replaced the throttle body on my car with one from the same turbo cx-7. The idle is very consistent now and AFR reads at a consistent 14.5. my STFT are also no...
Maf o-ring looks good and the connectors look good. Car idles way worse with maf disconnected if that rules anything out
I can't get a log of the maf right now since my buddy has the obd2 port, but I found a log of me driving around before the throttle/rough idle.
