Has anyone on here ever dealt with idle misfires on their 2012+ JK’s? I recently got a code for a misfire on cylinder 3, and noticed a quickly incrementing miss at idle. I went through th usual suspects and replaced the spark plug, coil pack, injector, intake gaskets, checked compression (160psi), checked leak down (less than 4%), checked cam lobes and valves, replaced the upstream O2, and nothing has helped. Wanted to check the group to see if anyone else had recommendations.
