Hey Scotty, I have a 2001 Infiniti I30, with 276,000 miles on the vehicle. It have a P1440 and P0420 code. Which code should I take care of first and how should I go about doing it?

If you don’t have to worry about emissions or anything depending on where you live neither of them will really hurt anything but to choose I would lean towards the bank 1 cat
