Focus Mk2 Misfire

[dj0nes]

Hi all, im currently suffering major engine problems the car is undrivable at the moment, it is misfiring very badly. It started earlier when it was stuttering here and there but ws still drivable so I took the leads and plugs off to check things over now it's a lot worse and basically sounds like a muscle car but goes like a tractor.

I've started the car and left it idling and unplugged a ht lead one at a time and it appears cylinder 3 has a very very weak spark and the rpm of the engine doesn't change regardless of whether i have the ht lead of plug 3 or not however I thought 3 & 3 were linked and fire together? cylinder 2 has a good spark however, I've ruled out HT leads by trying a new set.

I have come to this conculsion by listening to the sound of the spark in all cylinders 1 & 2 is noticeable where 3 is quiet.

Coilpack??! I'm just finding it weird that cylinder 2 gets a good spark when cylinder 3 appears not to.
