Be replaced all my spark plugs. Did compression test. Swapped coil packs. Replaced injectors on 5,6,7,8 still missfiring and doesn't idle right. Any help would be appreciated.

P0161-O2 sensor heater circuit bank 2
P0307- cylinder 7 misfire
P0308-cylinder 8 misfire
P0300- multiple misfires
It could be but why only those two cylinders. I put heet in it in case.
My last 5.4 had a moisture problem. I now have a 5.o. And I have not experienced this problem.

That's the bad two cylinders... How's the compression read? Did U do a leak down? When u pulled the plugs were they wet? Gas? Coolant? Lean crispy? as I like to say.
It could be a crankshaft position sensor maybe... U likely. Just remember fuel, air, spark. Verify those. Compression seems to help too.
5.0 are great engines. I am sure it's fine. Double check and triple check your work
