Had a CEL popup recently and it reads catalytic converter system efficiency below threshold b2. We reset it via an obdII reader and reappeared about 40 miles later. Before getting a new cat, I want to try some things. I just dumped some Techron cleaner and refilled with gas today. Was wondering when I should reset the light (after burning the tank of gas or now) and if I should disconnect the battery instead of a reader reset?
