08 civic coupe ex-l po420 code HELP!
Hello
I recently had my check engine light come up, and I took it into a PepBoys to scan right away. The po420 code came up which is a low efficiency in the threshold bank #1 of the catalytic converter. I hope this is just an o2 sensor or maybe the cat needs to be cleaned. Can anyone help me out with this?
