Problem sorted

Replaced all the spark plugs (they looked terrible) and swapped the number 1 coil with the number 5, just in case it was at fault and I needed to get at it again (number 1 requires the removal of the intake plenum etc, bit of a *****). One thing I did notice was that there was a bit of water in the bottom of the number 3 plug tube, not sure where this would have come from

There is a bit of plumming in that part of the engine bay, so maybe there was a leak, or someone was a bit careless in the past...? Anyway, mopped it up dry by feeding some paper towel down there. It's back to running on 6 again, and the computer's engine warning went away after a good drive

Oh, in answer to my original question...it seems the V6 coil pack (GTA at least) just has a little spring inside to apply some positive pressure on the top of the spark plug. The TS ones push onto the spark plugs.
