I had exactly the same problem a small intermittant miss at idle, it slowly got worse. It ended up being a stuffed coil pack, $70 later good as gold.

Does anyone have the translation for the(series 2) fuse box thats located behind the coin tray?
I am having some trouble with my cigarette lighter and I would like to check the fuses. Any help would be greatly appreciated. Cheers Nick.
