Misfire Codes P0304, P0303, P0305
2005 CLK320, M112 Engine, A209
Got a code P0304 initially. Swapped #4 Coil with #2 Coil. Erased codes and check engine light came back on. This time P0305 code came up. So, then I swapped that coil with #3 Coil. Erased and re-tested. I get P0305 again.
I've searched forum and not seen a thread where the codes jump from cylinder to cylinder.
Any ideas suggestions would be greatly appreciated. I just got this car at end of summer and only put 500 miles on it.
Thanks!

I would put the coils back to their original position and see if it throws the original code. If it does, I would buy a coil and replace 4.
I think a misfire can also be due a firing when it shouldn't as well as not firing when it should.
