All right I figured I'd check with you guys to see if I could figure out my current issues. Needed to swap out my spark plugs and ignition coils on a 2016 f150 2.7 l EcoBoost turbo. Got to pack off Amazon (KAX) that had good reviews, pre-gapped plugs that all checked out and packs that looked exactly like the ones that were OEM on the truck.
Spent yesterday morning at my dad swapping them out, and I got a check engine light. Brave it back home and could detect misfiring, and jump back on the Amazon and ordered a BlueDriver Bluetooth diagnostic tool, which came in this morning, and I'll add it's pretty awesome.
Anyways, I'm getting error codes for coils two and three which are on the passenger side, middle one and the one against the firewall.
Did the swap trick on number two with one and I'm still getting the same error and nothing where the original number two was in the one slot.
Friday though when I was going to get my vehicle inspected, my damn truck wouldn't turn on and I had to diagnose it in the parking lot, and ended up being a relay on number 66 that goes to the power control module. Swapped it with something that wasn't being used and fired right up.
I don't know if I got too bad coils, or if maybe I'm having problems with the PCM. Checked all the wiring harnesses, connectors for seated tight, I mean I was gentle with everything swapping stuff out yesterday.
Ended up running the stupid AutoZone today and the only coil pack they had on hand was $75, and come to find out they charge $120 for a motorcraft. When the hell did they skyrocket in price for over the counter sales I have no idea but I'm not paying that.
I'm waiting on the damn engine to cool off for me to go back out there and at least try that other one and see if I can get rid of one of the codes.

I've swapped out coil packs and stuff on all of my f-150s and I've never encountered something like this. I'm just worried it might be a bigger problem. I was also getting misfires prior to swapping everything which is the reason I went ahead and embarked upon this.
Any help would be appreciated.
. While I could fight her on that and break her will eventually some other nerds turned me onto this. I very much like the idea of a simpler car you can do stuff with yourself in the garage. As opposed to today's indecipherableones.
