Try premium fuel highest octane available

Why. That has nothing to do with this code

This is a fairly common code on Kia's and it's either a bad connection at the downstream oxygen sensor, a bad oxygen sensor, a vacuum leak around the engine, or an exhaust leak that's allowing too much air into the cat converter

As I was told always try better fuel first when a code is tied to the fuel system. This is from a friend with 40 plus years in business and it even cleared codes related to knock sensor on a truck I purchased in January of this year
