Were you pulling a PO420 code because of this? I'm also getting a EVAP code saying low purge. Not sure if sucking in more air is making the cat below efficiency code and not actually being the cat. What is the inspection gasket near the PCV valve? Mine looks like yours dirty with oil and stuff. I replaced the PCV but the little flat part behind it looks like a gasket sticking out a little?
It took about an hour, and no. That will not trip that code. The only other thing that will trip that code is the oxygen sensors but other than that it would be the catalytic converter. @krakenhits1587
Respectfully. the only thing i don't particularly like about this video, it was helpful, but everything was sped up and for someone that may not know what to look for or what to do... speeding up can make it not nearly as helpful as your content could be.
