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.
