Ok thanks for your input.

Towy & Merv, my engine came with no dizzy so I bought the dodgy one first, as you did Merv, had problems even starting so ditched it for the Msd. That fixed the no start. My issue is different to Towys in that once we're warmed up everything is fine. Even cold, startup is good, holds idle no problem. it loses power from idle to about half throttle, then clears with a boot full of gas.
Funny that if I stop for a minute when it coughs then proceed it seems to fix it.
I'll recheck to TPS voltage again, I have done this already on first setting up the engine. It was within specs then.
On the ECU, I read that they're pretty bulletproof, maybe that's next.
