Hi all - I've managed to break my V8 again.
Yesterday I fitted new spark plugs and it was going well (apart from an LPG switching problem but that's on another newsgroup) and today I fitted a new radiator. Upon restarting the engine it was obviously running rough and if you put a load on it by pulling away slowly it is quite obviously way down on power and missing - it feels as though two of the spark plug leads are crossed (which they aren't) but that's the best approximation that I can give to how it feels/sounds.
I've checked and rechecked plugs, timing, HT lead routing and that all connections to and from the coil are OK. The problem is also apparent when running on LPG so I've put it down to something electrical rather than fuel.
My reckoning is that I have disturbed something when fitting new rad - I did have the dizzy cap off to get access to clamp bolt for power steering pump and I was faffing around near the front of the coil. Like I said I have looked at all the leads/wires and they all seem fine - can anybody help with where to look next?
