My nemesis

Hi All, i have a 2008 Vitara 1.9ddis. The issue im having is that i have to start it with easy start and if the revs fall below1800 then the car stalls out. Initially it showed the fuel rail pressure sensor and i changed that but still the same issue. Would anyone have any ideas? Many Thanks In Adva...
