welcoem to SS...1st off no such engine code,the 4 pot is B207...P0300 random misfire,P0304 cyl4 misfire,P1312 ionization module code(also caused by failing coils)...when you swapped over the coils did the P0304 code stay where is was or did it move to a different cyl..
Yeah the code has always stayed on cylinder 4 , tried swapping coil about then swapped injector about and all still came back up with exact same codes , sorry for my nievety not too sure about all the mechanical stuff lol
you might want to take a read of this thread,problems with the intake valves... , this is mainly a US based site...
swap the plugs too, see it it moves with the plug
