T4, hideous misfire.

Hi all, I've had the odd bit of stuttering the last few days, figured it's probably in need of new plugs so ordered a set, they're not here yet, but it's got worse, as the video below shows.

I've had the plugs out before starting it this morning and number 1 was really sooty, the other three all fine, made no difference, then I tried with number 1 lead off, obviously still the same apart from it doesn't clear when you raise the revs, then I tried disconnecting the coil pack on number 4 that also feeds 1, pretty much no change, obviously rougher initially as there's now 2 cylinders missing, but it's the same running as towards the end of the video before I raise the revs again, to me it sounds like it goes on three and then down to two, hence the worse running nearer the end of the video.

EDIT: then I swapped the coil packs around and the problem has moved to 2 and 3 as I hoped it would, so it's a dead coil pack.

At least its an easy fix then.
