I recently changed the plugs and COP on my 2013 Edge, I used aftermarket COP's not Ford. . Today we got 4 DTC's, P0304, P0351, P0352 and P0354. I pulled the coil for number 4 as this was the easiest to diagnose and found the coil shaft was cracked all of the way around abount half way down the shaft.
I installed one of the original coils and cleared the codes, the car runs fine.
My question is will the cracked coil cause the other codes - "Primary/secondary circuit malfuntion" in the other cylinders? The firing order indicates that the other cylinders with issues fire on either side of the bad coil.
Thanks,
