If I remember correctly, you had installed aftermarket COPs, FordTechMakuloco advises to never use aftermarket COPs, too many issues and quality control. If you haven't already, I would go back to Ford OEM Coil Over Plugs.
I did at one point use aftermarket and since then have only used oem motorcraft parts. At this point I'm at a loss to what it could be. I did reach out to him to get his thoughts on the matter just waiting on a response now. I've just changed the high pressure fuel pump with no change. 🤦🏼♂️
You should take a look at this channel, ru-vid.com. That guy knows his stuff. Heck, his shop, I believe, is close to you. If I was close to his shop, I would take my truck to him. Watch his vids and you will know that he is the man!
1.) Make it a-FORD-able. 2.) Engineer parts to have a lifetime that falls off just out of warranty. 3.) Manufacture TONS of replacement parts. 4.) Profit prey on unsuspecting victims.
