If its had recent plug change these things have very sensitive coil packs and break down all the time, they are also sensitive about plugs too.

Make it misfire and disconnect each coil pack in turn to define which one is missing then to see if it is the coilpack move the coilpack to a different plug if it follows the coilpack then its the coilpack if it stays on the plug then its related to that plug (could still be something else though and not just the plug)

What plate is it on? Earlier ones had the ignition control module mounted on the airbox, its a common problem that the plugs/wiring can get a bit dodgy leading to this leading to little or now spark at all, try with the engine running just moving the plugs whist still attached see if that remidies it. Its more than likely what guy said though.
