Time to beat the dead horse. I’d be looking at fuel pressure first and foremost

Keeping this updated as i continue to diagnose.
So i changed the MAF sensor... Within 90 seconds of restarting the car it pulled 3 misfire codes it has never pulled and one IAT sensor volt high code. All misfires were on the odd side. I think its really strange that through several logs and lots of testing the car never pulled a code until i changed the MAF??
I think its somehow related to the coil wiring harness on the drivers side... It looks fine but thats the only thing that isnt new and it makes the most sense. I ordered one from summit today.
Ill still be looking at the fuel pressure as well.
