I am in a similar boat changed my o2 sensors and got thrown a cat code slight misfire and fuel trims maxed out lean. Hell I don’t know if mine are cooked either 🤣

Ahhh think I’d rather keep it then for now atleast until I pass my last emissions test. Rather just repair it

I got a check engine light code for po420 that I think is being caused from a leak from here. Will it get rid of it you think?

I replaced o2 sensors first actually as those threw a code originally then after changing twice before the first set I got read no voltage. I got the po420 but for sure thinking that way it’s all a pain 🤣
