Hmm
I must plug in again. And check out the readings. I don't mind buying 4 sensors, but don't want to throw them at it for the sake of it. The only fault / dtc was O2 sensor after cat, bank 1, voltage monitoring.

But if it was to drive better I'd get them. It seems to have a fair old smell of fumes on startup, but I still get 22 mpg cruising.
