JDM Hatch running rich/P0420
Hi all,
Looking for some help with my JDM hatch. Car threw up a P0420 code when driving steadily on the motorway - cat efficiency low bank 1.
Fitted a new genuine front Lambda and cleared the code. Car was ok for a couple of days but then got the same P0420 code. Smells like it’s running rich and using a ton of fuel (more than usual for a Subaru!)
It’s booked for mapping next week (for uk fuel) but is there anything else I should be looking at in the meantime? Hoping it’s just the map needs looking at as it’s a completely standard car with the JDM map on it.
Any thoughts?

well, checking the receipts this evening that came with the car and after a bit of Googling and searching ICP, turns out the rear lambda the previous owner put on the car is for a forester STi!
hoping and praying that this was the problem all along. Correct sensor ordered, fingers crossed
