I would definately check your fuel pump (for making sure that gas is definately pumped into the injectors when you need it) the fuel accumulator (for keeping the pressure of the gas vapors going to your engine allowing it to have warm starts in even the coldest weather) the fuel filter (too much carbon could be in your fuel system now that little to no fuel may be able to get through - esp. at low rpms) the fuel distributor and the injectors as well as the fuel lines - (to make sure there may not be a clog of carbon somewhere that may be too tough to get rid of - usually you can check for this by listening to the sound of the gas passing through the line) I own a 90 VW and had a prob with this for awhile and it turned out to be the fuel pump and accumulator (already replaced the filter before so that helped a little) but hopefully this information becomes helpful!
