2000 Toyota 4Runner 2.7L MIL Lamp on
This vehicle has a P0420 cat efficiency code it also has two cats rear o2 is behind both. Just looking for anyone who's dealt with this and how they addressed it. Replace one over the other? Replace both or is there a way to verify which one is the issue? Than...
