Hi reaching out today for some help. All started after a heavy rain car went from running completely fine to a rough idea. Put ob2 on got a p0300 then p0107. Replaced the plugs and wires same issues. Checked all the plug wire connections to the ignition coils shockingly 4 of 6 where arching, cylinders 1 and 4 where not. Changed out the number 3 ignition coil with a new one hoping 1 and 4 would fire unfortunately no replaced with original OEM. After the diagnosing I am stuck at a loss. Codes currently being generated are none car has not been moved since OEM ignition module 3 was tested out with the new. No spark off of wires 1 and 4. Rough idea after started and throttled. Icm replaced less than a year ago plugs and wires all the way around a week ago . EGR valve less than a year replaced with the vapor canister purge valve. Parts on the way maf sensor , map sensor, pcv valve. Looking for any other helpful info on what this issue might be. Thsnks anyone In advance.

If you still have no spark on a single coil after replacing or moving the coil its a bad ICM. Doesn't matter if you replaced it a year ago or a week ago.
