My daughters 1.6 Vetec Fiesta has just started playing up when cold. It's fine when warmed up but hunts and nearly stalls when idling straight after starting. Presumably it's the ISCV or auto-choke (if they still fit them). Can I adjust it and where on the manifold is it?
There is a screw which sets the tickover but it doesn't have a head (if that makes sense). It sticks out of one side of the casting against the linkage but not the other (where I would expect the head would be).
