Megane 1.6 16v K4m

Hi everyone, I'm having trouble with my Megane. When it's idling, it misfires a little, like there's a short in one of the ignition coils. If anyone knows a way to test the coils one by one, I'd appreciate it. I was told to disconnect them one by one, but since the problem is minor, I don't think I'd notice any difference. I'd appreciate any help. Thanks.
