Potentially PCV related but it should throw a P0171 code with it.
Pop this cover off the engine.

Once off and the engine is running check for suction at the PCV shown in this next pic. There should be 2 small holes towards the front and back. If you have suction there then the PCV system is damaged / faulty / broken. At a bare minimum you likely need a new valve cover and possibly further PCV system repairs.
