P219A code please help

[Jwxcf]

I recently swapped a 2013 5.7 into my 2014 also had a 5.7. It runs. It idles fine. Giving it gas it’s fine but when I go to drive it, it starts to misfire/ cut out. Code read -p219A and other misfire codes. Bank 1 air fuel ratio imbalance. I have no clue what this may be. We have been testing injectors and everything. I do not believe it’s the cam and lifters because I’ve had the problem before which was the whole engine swap reason. And it was a constant misfire which makes sense. If the cam is eaten away or a lifter is collapsed then it should misfire most of the time if not all. Has anyone else had this problem and what did it end up being. I’m really hoping it’s not that the engine just won’t run right on a 2014 wiring harness. There’s gotta be a fix. I mean people put 6.2s in cars that dodge doesn’t even make and they get them to work. There’s gotta be a fix for this

I have no clue what this may be.

I figured it out….. literally back to the basics that I overlooked cuz I was overthinking about it. The damn park plugs and coil packs on 7 and 8 were awful. Caused the non consecutive misfires. And I assume it wasn’t burning all the fuel so that’s where the p219A came from the o2 sensors were reading too much fuel…. Thankful it was simple

Coil cleaning pics

Yea i know my picture taking abilities suck,lol Hopefully you guys can tell how i go about cleaning up the coils from the pic's. The first pic,is just a pic of everything disassembled.If your truck has the resistors under the spring in the coil towers,you'll want to remove them and clean them...
