P0358 Code: Ignition Coil H Primary/Secondary Circuit Malfunction
I recently had a code on my 06 V8 saying that cylinder 8 was misfiring. I went through and replaced all of the spark plugs, and I replaced the ignition coil for cylinder 8.

After I did this, the initial code for the misfire went away. But now I have this code P0358 Code: Ignition Coil H Primary/Secondary Circuit Malfunction

I did some research and saw that most info said to change out the ignition coil, which I already did.

Anyone else have any experience with this and are willing to share some info on how to solve this?

Thank you.

Swap the coil with another one and see if the code triggers again and follows to the new location, if it does then the new coil could be bad out of the box.
