Re: oxygen sensor (dxdriver)
Yes you also need a cat, o2 sim, or OBD1 conversion if you don't want a CEL. If the secondary O2 doesn't pick up a catalyst around it, it will throw a code. I don't think the secondary O2 affects performance though, but you will fail emissions, but without a cat you will fail visual anyways.
