Thanks GTLEGEND.
As I've dug deeper I've opened a real can of worms for myself.
The diagram I posted comes from the workshop manual for the 1600 ZM engine. Ahhh - but which ZM is it? Many variants, as it happens.
Depends on the car maker, the country, used in later cars - eg the Focus.
So - my car never had tumbler butterflies, but I can see in the head casting where provision had been made for the butterfly spindle.
Back to my original performance/lack-of issue:
What is in the intake path that can suddenly change and produce the extra performance?
As mentioned earlier, the car spent a couple of nights in zero deg. temps.
Next time I drove it .... whooosh ... over tall buildings in a single bound ...
Obviously something had changed ie contracted c/- the cold, allowing 'everything' to work properly again.
A few weeks later - back to crawling up those same hills.
Arrrgggh.
Suspecting vacuum related.
Cheers.
