This engine has a separate coil per cylinder mounted on top of each spark plug. Ignition coil failure is common and even intermittent, random ignition coil failure is common with this engine.

I have an 04 LS and had a misfire in coil #6, I replaced then a misfire in coil #1, I replaced then a misfire in coil #2, had to take to dealer because intake has to be taken off to get to #2 & #3 so I had them replace both. I suggest you buy 4 of them online for around $20 a piece and replace yourself (it's easy), the dealer charges a little over $100 each for the coil pack. Then it's 4 hours labor to replace #2 and #3.
