There have been others who have broken the coil pack bolt, but none that ever found the bolt by itself (as far as I know). I think your stuck buying a new coil pack.
BTW, before you start cleaning the throttle body, disconnect the battery (30-45 min). The PCM needs to be reset to factory default setting. The idle may be a little rough at first, but should smooth right out. If not, you have other issues.
