General 1.2 8v juddering (misfire??)

[JTG0710]

hello all, over the last few weeks i have noticed the punto become very jumpy and juddery when idle, both from cold and hot, sometimes in traffic, the whole car would shake from this, recently been serviced, plugs oil, oil filter, air filter, all leads been checked, however this problem started before the service.
please help many thanks

Failing coil pack is favourite, worth a try before delving into other mechanical stuff.

how would i check whether it is failing, surly there would be a huge diffrence in the engine as it has not failed completly.
many thanks

Buy a spare... always good to have one, not uncommon on all makes these days. Then swop one existing coil-pack for the new one and do the same until you find which one is the culprit.
