Thanks Kirkynut.
Well it's turned out to be not good news
I caught up with an old RAF colleague of mine who was always a bit of an ace with electrics and he went over a whole load of tests.
His code reader found "random multiple misfire detected" and on further investigation found the front O2 sensor reading a high voltage indicating a rich mixture.
He routinely went through the plugs coil packs and HT leads and found them all acceptable, so went on with a compression test which gave the following results:
#1 Cyl 9.75 Bar (141.4118 psi)
#2 Cyl 8 Bar (116.03 psi)
#3 Cyl 9 Bar (130.534)
#4 Cyl 9.75 Bar (141.4118 psi)
So he thinks there is a good chance that there are burnt out exhaust valves on 2 & 3
