2014 QX80, has random misfire. 178000 miles. Need to tune up. Seems like cylinder 3 ignition coil is not firing. Unplugged coil with no noticeable drop in RPM. What ignition coils and plugs are recommended?

thanks I’m advance

You might want to swap coilpacks first, to see if the issue follows. It could also be a fuel injector.
