I had a shudder at low idle turned out to be the top belt and the idler pully, replaced both and all was well, I would also check the fresh air filer next to the oil tank, this filter is not always changed as often as it should. The engine will always have a small vibration at low revolutions seems to be inherent in the model seems to even out at about 1800 rpm. I have never changed a coil pack, there is plenty of info on this item on youtube, these do give issues when they become faulty.
