removing o2 sensors in a magnaflow cat back
Well after putting in headers got code 0420 so either I tune it out but my flashpaq wont do that or I put in O2 filters for now. Thing is the O2 sensors are in a Magnaflow cat back system and are tilted up out of the way. Anyone do this and what tool did they use. I tried using the Autozone crows foot tool but that was a no go it kept slipping so I stopped.
