Well snap. The jk has finally had a issue. 140,000 miles and it started having a misfire on cyl 4 a day ago. Looks like I figured out what to do tomorrow

Plugs (if not done at 100k), wires (dist based), or COP#4, or coil pack (assuming dist less). Possibly fuel related if it's also got a random multiple code (p0300)
