Hello my name is ***** ***** I will assist you. Move the first two coils and plugs to the last two cylinders and erase the codes. If now you get a po304 and po305 you have bad coils or plugs i personally replace them together. This is the most likely cause. If you move the coils and plugs and still get the p0301 and p0302 we can look further. Please rate me if you are satisfied with my answer. Thank you and good luck. I will keep this open in case we need to do further evaluation.
