I have a 2004 A6 and I was wondering what some symptoms are that shows I need to change my plugs. My manual says to change them at the 75k mark and Im at 65k now, but I have noticed that sometimes while stopped at a light my engine will stutter for a second and the rpm's will drop for less than a second and then be fine again. Does this sound like a plug problem?

Thanks!
