Sorry mate i'll give the you quick spec of the car, L8, T38, Siemens injectors, wasted spark, msd chip, 4x4 inlet the car already has the 4x4 throttle as it was running with it before and was set with a multi metre so is smack on the setting.

It's a wierd one really as the car fires but sounds like on 3, correct firing order and plugs were new before the winter with the top really tight, 909 leads it's something simple i know but i'm racking my head thinking.
