My 2011 Genesis coupe 3.8L GT has an issue that’s been going on for a year now. It has a P0014 code that’s causing it to misfire if I go above 60 mph for more than a few minutes. So far I’ve replaced the Oil Control Valve Exhaust side, The spark plugs, the coil packs, done an oil change, and replaced both camshaft position sensors. The code has came back after every single one of these fixes. I’m currently out of ideas.
