P0305 Error - Dark Spark Plugs

[michaelt]

Hey everyone I have a 2021 Wrangler Unlimited Sport 3.6 with 30k miles, I got a P0305 error today on cylinder 5.

So I pulled everything apart to replace the spark plugs but they look pretty dark.

The EGR looked burned when I pulled it out too.

Before I put everything back together is there anything else I should be worried about or replace?

Plugs look ok

Plug looks fine. You’ll likely need to continue to diagnose the misfire, that’s probably not going to fix it unless you see a crack on the other side. Might as well move the ignition coil from 5 to another more accessible cylinder on reassembly.

Welcome to the Forum!
That spark plug looks like new! Unless a spark plug fails, they don't need to be changed until 100K miles.
