there was only 1 cat and two sensors. the first Pre-cat sensor is stock all stock and i did not rewire anything on it. All I did was plug it into the downpipe. The second post-cat sensor is the Bosch, and the wires might be wired wrong and it's plugged into the catco with bung behind it.

so Bank 1 sensor is the second post-cat sensor? that would make sense because it is a universal Bosch and i'm not 100% sure on the wiring.</div>

Bank1 sensor 1 = precat bank1 sensor 2 = post cat.

When the car comes stock from the factory, it has one on the downpipe between the manifold and the cat, then one after the cat.
You didn't relocate o2-1... You are only monitoring cylinder 4 then? I had to relocate the o2 sensor to get it in the full flow of the exhaust where the 2nd one used to be

Webtech says your p0134 = bank1 sensor 2 inactive. That's the 2nd o2 sensor, after the cat.
