Hello,
I have replaced the cat about 4 months ago and O2 sensor, recently replaced the fuel pump and now it’s pulling the P0420 code. I’ve put more money than it’s worth into this car and I’m not willing to replace the cat again. I JUST replaced the cat so what is the possibility this is the cat again? Is there something I can do to fix this?
Hope you get this sorted! Let me know how it goes, I’m always curious! Good luck!
