Cylinder 3 misfire

Hey guys. I search an couldn't find anything on my misfire. I have a cylinder 3 misfire and idk what it is.

Hers what I've done. I've replaced the spark plugs and coil pack. Fuel filter hasn't been changed yet, but I bought a new and will be on soon.

If this doesn't fix it what else could it be? It runs fine and I can barely tell that it's misfiring. Just a small tiny shakin if the engine. Nothin major but I'd like to fix it before t is.

Thanks guys!!!

Jeep for life!

You can move #3 fuel injector to a cylinder that is not currently misfiring. If the misfire moves to the cylinder with that fuel injector you know that is your issue. How did your old spark plugs look? Any carbon tacking on your old coil? You can to a compression test to check the bottom end of your engine. You can take your valve cover off to check the top of your engine.
