There’s other things that I would suspect before computer. If it’s not the coil, I’d do some troubleshooting first before launching the parts cannon at the issue. Fuel pressure under load is one thing. Spark plug gap and condition of plugs. Compression test, and several others.

I've checked all the wires while it's dark and have observed no arcing or cross fire.

The fuel pressure was set at 38 during my tune and has always remained consistent. Spark plugs are new and wires are "newer" and I had a valve job less than 1k ago.

Ill drive it to a car show this coming weekend and will be able to determine if the new Motorcraft coil solved the issue.

Good discussion.
