Chasing an idle misfire

[Worxman]

06 LR3 4.4 with 92k miles. Started getting a misfire noticeable at idle, but not in park or while driving. No check engine light, no codes on the GAP tool. Researched it and first tried the throttle body and MAF clean...throttle response was noticeably improved, but the misfire continued. Next decide to go ahead and change the plugs since they were presumably original...misfire continued. This morning upon start up, check engine light came on and boom...cyl 3 misfire appeared (using the GAP tool and app). Went to Autozone and grabbed a coil, slung it in, no more misfire. Hope this helps someone else or at least makes your good time chasing this just a tad better.
