Connect some OBD reader with live data. You should easily chase the one that is missfiring... I think TOAF does not support the live data for KV6, but i am not sure.

I had that trouble on my previous car and everytime it was just a cable, not the coil. Also, check the spark plugs, maybe it's replacement time...

You say you have checked the plugs. Do you mean those important plug GAPS ??
