Hi so not having any major issues with the car but it just through a P04AF code and the research I did told me it was a faulty PCV valve, I’m no expert though so I’m not sure. Has anyone else had this code show up and did it turn out to be anything else. Only thing my car has done so far is fluctuate rpms while idling.
Also if it helps I have a 2017 Wrx.
