i had bad coil packs and i never got a check engine light. If u know you have a plug fouled just change them all out. If you still have it start testing for the bad coil pack.

+1, 10 dollars and 30 mins later! Much cheaper than guessing or getting 70 dollar a piece coils.

sounds like you may have "nipped" a plug, whos' plugs are they and what gap?
bad COP's will Not always throw a MIL and a plug thats been nipped by the use of Nytrous can be intermitten, depending on "how" it fouled.....
