hey i've got a 2008 dodge charger srt8 and my check engine light is on
i've got 4 codes and i believe they are related to each other and the case could be one or two things
p2096 Downstream fuel trim system 1 Lean
p0430 catalyst efficiency (Bank 2)
p0133 o2 sensor 1/1 slow response
p0420 catalyst efficiency (Bank 2)

please let me know where im supposed to start for the repair process. any recommendations, instructions or pictures will be helpful. thanks

Have the O2 sensors ever been replaced I would start there all 4 new Mopar sensors. Disconnect the battery while changing them and see what it comes up with after a few test rides

p2096 and p0133 are definitely complaining about the Bank-1 O2 sensors. Bank-2 is complaining about the catalytic converter. As ktmtigger said, replace all four O2 sensors with OEM Mopar sensors. Clear the codes and see which, if any, codes get logged after the O2 sensor replacement.

I've started making non-fouler adapters you can install with your rear O2 sensors to bypass the possible faults in the cats. If you're interested, inbox me!
