Im guessing you know po308 is a cylinder #8 miss, if you replaced plugs and wires after
the code, try moving the coil and injector from that cylinder to another cylinder and see
if the miss follows to the cylinder you swapped with. if it does, just move injector or coil
next time and see which one makes the difference. won't cost anything.
