Anti-Foulers suck and are a hokey fix for not relocating the o2 sensor.

Default hey bob, think all the codes are just from the foulers? ive seen cheap o2 sim boxs on ebay do they

work? anyone tried em?

whats weird is one of the codes is for my pre cat o2 which was fine before the swap.

unless that bank is post cat?

thanks
