Here's 2 logs, take a look at the afr for bank 1 and 2. Both logs are just of me cruising, bank 2 seems to be worse than bank 1

Not looking good, could be leaking injectors.

Have you checked your plugs for leaking injectors?

Yeah the spark plugs were all black after 5k miles, couldn't tell if they smelt like fuel, I installed new plugs and after 100 miles they were starting to turn black
These were after 5k miles
