First (legal) drive and engine issues

[Merv and Sharon]

True. I recall recently that Rob at Tambourine had an EEC that failed. That is unusual. I sent him one of my spares and all was fine. I have another one of those too but check the TPS first.

I had a similar problem years back. I had a dodge with a 440 magnum (spec) motor. The custom headers went to some weird places due to the engine being a tight fit. They used to get real hot. The spark plug leads caught fire when running the motor in. There was so much heat that the fuel was vapourising in the lines. It went away at full throttle because there was enough flow to keep the fuel cool but when just crusing it ran like a dog. Took me ages to work out what it was. Anyway, I moved the fuel lines and fixed the problem.

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.
