New Wires/Plugs and still throwing P304
Replaced wires today because I had an arcing wire on cylinder 4 which was throwing P0304 code. Now, AFTER changing wires and plugs (I used Kingsborne 8 mm wires). I still have a misfire on cylinder 4... Original plug removed from cylinder 4 looked normal (no oil or coolant).
The other weird thing is it stops misfiring above 2500 RPM and runs like a bat outta hell
Any ideas? This is frustrating

I am starting to see a pattern, we have had a rash of people do a tune up using those plugs and they all have had a single cylinder mis fire that cannot be tracked down or cured.
Do yourself a favor and go and buy Champion plugs, the cheap copper ones and put those in the truck, clear the code and see what happens.
I am betting that your mis fire goes away.
