Have a new to me 2008 jk 3.8. it recently started coming up with a misfire cylinder 6 code. I replaced the wires, plugs, PVC valve, and coil pack a few days ago. Code came back on today. I'm guessing injector is bad, not sure what else it could be.
A few weeks ago I replaced the lower intake manifold gasket but engine ran great after that. Also replaced the heater core because it was leaking coolant inside the cabin.
