The engine is smooth and perfect while driving but at idle (stop light) it will drop one cylinder. Only way to get it firing on all 6 is to shut it off and immediately fire it up again. All plugs and coils replaced, same problem.

I should add that this is a USA car built for the Japanese market and this problem does not show up on a North American scanner. Japan uses different computers.
