The focus does judder its a matter of how much commonly the pcv valve or incorrectly gapped plugs are the cause plugs come pregapped at the old gap of 1.3mm it should be 1.0mm also dielectric grease should be smeared on both ends of the leads coil end and plug

It seems to do it when driving, about 50ish and when it has warmed up - petrol treatment seems to cure it for a day or so

Could be a clogged fuel system, such as a new fuel filter, or a treatment to clear the injectors etc.
