Hi. Just to let you guys know, I had this same problem (when the clutch was depressed, and foot taken off accelerator and onto brake - the engine died) in my 97 Lxi Felicia. Being a student and having no money I experimented with it quite a lot (with varying results!).
Today, after reading this excellent forum for the first time, I cleaned the throttle body with 'Wynns Fuel Injection and Carb Cleaner' and tightened the accelerator cable. This seems to have worked (fingers crossed). All for £4.99, as opposed to £75 down the local Skoda dealership.
This has made the car idle at higher revs and instead of the revs dropping off when the clutch is down it now remains stable. As the accelerator is more responsive it feels like a better drive (and is easier to recover from those stalling moments). I don't know how this will effect fuel consumption (if anything), but if Felicias not stalling I'm a happy man!
