Did you just do downpipes? maybe they are in wrong?

Franzein · 06-07-2018, 06:10 PM

No downpipes were on for long

That's not a cat efficiency code, that's a faulty O2 sensor code. In my experience, those O2 sensors are extremely fragile.

Any clue which post cat because I just replaced the post cat drivers side one last month

RocketSurgeon · 06-08-2018, 10:53 PM

That code is for Bank 1 post-cat, which should be the one you just changed.
What sensor did you put in? Did you go OEM or aftermarket?
