PULLING MY HAIR OVER A P0301 code!!

I've decided as we're entering the Texas summer, I'll just bypass the heater core for the time being and continue chasing the misfires.

Also, where does this heater hose fitting go to?

Connects to the rear heater pipe (one of two). If you don't have those two heater pipes then the fitting is not the correct one for your application.

I don't know. I haven't even looked yet. But thank you for the heads-up! I didn't know there were two possible configurations.

I went ahead and cut the other hose, that was perfectly fine because I decided to upgrade to the metal hardware. Go in, and never again.

I still have P0301 thrown BUT not getting an actual misfire on #1 per Real Time Live Monitoring. RTLM is showing a misfire on 2 and 5 which I cannot get rid of. I've changed the plugs and upgraded the plug wires to 10.5mm silicone. Placing a new coil at either position changed nothing.

I've attached OBD screenshots that are showing Bank 1 and Bank 2 Sensor 2 issues. I'm also showing only 43.51psi of injector rail pressure. Think I'll replace the fuel filter and see if there is any change. Either way, I think I'll gut the catalytic converters because, they just suck.
I also attached the Recorded Data in an Excel/Sheets format.

Took her to a mechanic and he just called. Cylinder #1 is dead.

Now what?!?

What’s dead about it?

Likely no compression.

I mean in all honesty.. you have 3 options.. Listed from cheapest to most expensive

1: Unplug the injector, and deal with it, ongoing check engine light, poor fuel economy, etc.
2: Find a used engine.
3: Get a new engine/ Rebuild your current engine.

I’m just wondering if they provided any info on what they think it might be.
