Ignition coils are a notorius problem with Maximas. Your first inclination that they need to be replaced is the Multiple Misfire code. Then you will get a hesitation and poor idle. If you car is over 70K miles and you know that they haven't been replaced, I would go ahead and save up for all six. But...if you like to fix things as they come...wait for the codes. You may or may not notice 1 cylinder misfiring...but you will definitely notice a severe drop in your MPG. You can visually inspect them or even run a meter on them...but that's up to you.
