P0284 after replacing head gasket

I just finished replacing the driver side head gasket tonight. It started after about 20-30 seconds of cranking. Now idles rough and it threw a P0284 code. Could this just be because there's air in the oil system that needs to be worked out or do I need to start troubleshooting the #8 injector?

Truck ran perfect before swapping the head gasket. Would just pressurize coolant and puke out the cap.

Check ficm harness plugs and injector harness plugs.

When i did mine i had the same problem, mine ended up being a bent push rod that killed the cylinder, once i replaced the bent push rod everything was good.

Discovered the exhaust valve bridge wasn't set right.
Berge Ford had both in stock. Replaced them and truck fired right up and now runs great.

$35 in parts sure beats a new injector.
