    I don't think my excessive richness problem is in the AFM. I unplugged my AFM and I still have the problem. I doubt my problem is fuel pressure, because when I gas it hard, it pings from being too lean.

      I had a similar problem. Check your fuses, my o2 sensor heater was missing (idiot who owned it before me) which would cause alot of carbon build up on cold starts which will eventually build up and cause it to not function properly when it does get warm.
