What could it be?

Ok heres the deal. My car hs what feels like a random miss but only under half or greater throttle, or in 5 or 6th under load(it will cruise fine in 5 or 6th just as long as you dont give it too much throttle). I am thinking it could be my fuel pump or something in the fuel system because it also takes a few cranks to start. I am wondering if it could be the pump. I pulled all the plugs and they seem to be lean. opti, plugs and wires are all new. any ideas?

What do both of the fuel trims look like?
