Help with P0456
I have a 2012 mustang v6, currently getting code p0456 small evap leak. I am trying to self diagnose as much as I can before having to go to a shop. Everything online is saying check hoses, and also gas cap. My stang doesnt have a gas cap, and from what I can see no cracks in the hoses. Anyone dealt it have tips on where to look? Could this be caused from axle back pipes I've put on it recently? Also there are no other codes popping up at this time.
