Sounds like not all the cylinders are firing in time, causing the engine to shake at low revs. Does the engine also threaten to stall at idle?
This happened to me recently in my 1.25 finesse. Took it to a garage and immediately they told me it was the coil pack that needed changed. The coil pack is responsible for generating the current that goes off to the 4 spark plugs. Coil packs sometimes inadvertantly fail, and the shuddering is usually a result of one or more of the cylinders not firing in time with the rest.
I was charged £100 to get it fixed, but you should be able to get a coil pack for £40-£50, they can be easily replaced yourself, it's located towards the bottom rightside of the block. But only do this if you're confident that the coil pack is the culprit!
