Cataclean fixed my problem 😊No more check engine light 😊😊

So basically replace a ton of shyt

[@daphrampa]

I have 3 different questions/scenarios I'm curious to know the answer to.
¹ What if I replace my cat converter completely. Will it rectify any other issues and get rid of the code?
² if I use the duralube severe treatment, but my check engine light is still on, does that mean or didn't work?
³ what's the cheapest and simplest possible solution to clear the code?
