All the sensors are new bar the lambda which is about 3 years old, it was running bad before it was rebuilt, but i never had that diagnosed as I was replacing everything anyway. It's a greentop engine, has no cat.
What I mean by there is no fault, is that I find it VERY hard to believe that something is broken if it's new.
Bar playing with the screw on the ECU what else can I look at, the phase sensor on the distributor?
