Anyone ever get P0420? I’ve got hi flow cats in my build and hadn’t ever seen this code ironically until right after I had my car inspected 6 weeks ago. I cleared the code, didn’t come back.
Yesterday went racing and the car ran great. On the way home, the code came back again.
Is this expected with hi flows in the heat? It was hot out and obviously racing puts a whooping on the cats. Maybe something that can be tuned out if they’re falling beyond the expected threshold? Car is otherwise running like a scalded cat and putting down 9’s easy.
