I had similar symptoms and it turned out to be a broken wire to one of the injectors. At least I hope so, because I have just finished fixing the wire and I will make a test drive tomorrow :)

The High Tension Leads; From the distributor to the spark plugs, and from coil to distributor.

They suffer a lot on the turbo due to under bonnet temperatures, so should be swapped out for new ones every couple of years.

Found the problem was head gasket and compression blowing into the coolant ' ie stuttering' no water in oil and only realised when checked coolant reservoir and bubbles galore
