Have no fear...you should be fine!

Does the car shake a bit too? Is the exhaust still stock, or of a high-flow design? Do you notice a miss-fire at lower rpms when a light-load?

Sounds to me like you have a bad plug, coil pack, or coil pack to plug connection. IMO, I would change the plugs. It is inexpensive and it will require you to pull the coil packs anyway and then reinstall them. Two of the plugs are a bitch to get at on the passenger side and if you are inexperienced with plug removal, be sure to have someone help you. It is possible to royally screw a motor by not installing plugs properly.

What you are seeing I think is a little bit of a miss-fire at idle. If you have a high low exhaust, it is more pronounced. If you let it go, it will eventually get worse and start to missfire while driving.

My car does this from time to time. I run copper plugs, so I go through them more often.

I could be wrong on this, but this is where I would start.

I agree with Blake....

For some reason people are amazed at what just basic ignition system upkeep and checkups can resolve...

Cars today have much more reliable ignition systems, but they still are not w/o fault. Personally, I think it is unrealisttic to leave plugs in for 100k as the manufacturers recomend. Back in the old days, changing plugs, wires, and distributors was always the first place to start when a car ran rough. These days, we all seem to forget that.
