Please help?! catalytic converter problems.. maybe.
So my check engine is on and I’m not sure if I should replace the catalytic converter for sure or not. I have a 2014 Jeep Patriot Latitude 2.4. I’m getting codes P0420 and P2015. I was told by 3 “mechanics” that it was my 02 sensors. I have had both replaced and check engine light still on. Was recommended to try Cataclean but I don’t drive it for the 10-15 miles they say to drive because I had an emergency I had to run home for. I haven’t had any issues with it turning on or driving really per se. but I do notice a little lag when I do accelerate. I’m not sure what I should do next. Don’t want to keep spending money for parts and labor and it’s not fixing the issue.
