Cylinder 5 Misfire code 98' Park Ave.

Hello All, new to this forum/site. I have a 98 Park Avenue and the computer is giving a cylinder 5 misfire code. I did a lot of work on my previous 89' Park Avenue but have never done anything to this one. Does anyone know what the typical causes and solutions to this may be?

Some potential causes are bad spark plug, bad wires, bad coil or a bad fuel injector. I would change plugs and wires first as they are the cheapest and will probably correct the entire problem. Bad wires often cause misfire issues.

Thanks GTP Dad, that's what I was thinking. I'll start with the wires and the plugs and go from there.
