When my car was almost new i had a misfire in cylinder 1..not exacly like you but.

i went to the dealer and they change the coil and plug on cylinder one, no question ask, even if my engine light was off by the time i went to the dealer.

never seen it since.

Well it's not all stock, I have an NX nitrous setup, cai, Mac Prochamber and flowmasters. So I don't wanan take it in if I don't have to. I'm thinking it's because I have the plugs gapped for spray. It only does it at idle (I think)

If it only did it once I wouldn't worry about it. Mine has done that before on start-up. Haven't seen it since. Your plug gap could cause it or a bad plug if it continues. If no light my bet is it wasn't bad enough to be a problem.
