Hi Paul, I had a problem with low power and found one of my plugs had a crack in the insulator. (But you said you have replaced plugs).
I found this by lying under the cobra with the engine idling (on stands of course) in a dark garage and saw the sparks external on the offending plug. (might be worth a try you never know).
I'd also double check all of your earthing points as that can give weird problems too.
Good luck
