Today we will show you how to work around two different emissions related issues with one awesome trick!
Issue 1: You vehicle is throwing a P0420 Code (Which indicates that the catalytic converter is not functioning efficiently). In most regions having this code will prevent you from passing vehicle inspection. Don;t worry, this super inexpensive trick can help!
Issue 2: Either you live in California (or New York) or somehow got your hands on a so called "California Car". These vehicles come equipped with a different, more strict, emissions system. The parts to service these California emissions cars can be up to 10 times more expensive than the regular parts... But do not fear! We are going to show you how to use regular emissions components on a California Emissions car and keep the check engine light off!
What is the secret to solving both issues? Spark plug foulers!
