P0174 System too Lean (Bank 2)
p0300 random misfire.
There are many possibilities to this problem, random misfire, could be, because of a intake manifold gasket, egr valve, vacuum leak, clogged, catalytic convertor, I suggest maniold gasket or vacuum leak first becuase you can knock both of those out at the same time. By spraying some carb clean in the area of the vacuum lines and intake manifold. These two usually run hand in hand. So you fix random misfire, the lean code should go away
