03 acura rsx type-s

Question

I want to buy a 03 acura rsx type-s but it has a po420 code how much will it cost me to be fixed?

Answer 1

This is most likely your downstream o2 sensor, behind the cat. part about 60-100$ can be done easy. You will have to heat the bung it threads into though w/ map gas or a torch to get it loose.
