Misfire in cylinder 4

Started the car after a walk to hear it idle in a way ive never heard. Threw up code P0304. Engine misfire in cylinder 4. Get home, and try swapping over the coilpack from cylinder 1 and 4. After doing so, the car is now giving me P0300, P0301 and P0304. Any ideas?

swapping the ignition coil has moved the misfire from cylinder 4 to cylinder 1. and because the micra ECU seems to store its codes it has probably stored the P0304 and the P0301 and that is what threw the P0300. chances are a code clear and a set of ignition coils will fix your issue
