Cylinder 8 misfire

[Duckhunter1986]

I have a 2014 5.3 with 117,000 miles and the check engine light came on 2 days ago. There Is a bad dead spot in engine between 1,000-1,800 rpm. I replaced plugs and plug wires at 105,000 miles. Is it common for the 8 cylinder coil to go bad?

Yes there are many posts 4 6 8. But really can be any. Check codes. All codes then replace and hope it isn't injectors. They arnt expensive but the work is oh and new fuel. Lines.

The DI injectors known to fail, as said they are not bad pricewise but they do take some work to get to as the intake manifold has to come off along with some fuel lines that probably be replaced as well.

Any update on this? I’m having similar issues with cylinder 8. 
 

I’ve damn near replaced everything and still get this misfire on 8
