Heell guys i have astra wuth z17dth and when i try to start it it cranks with compression then it losses then again cranks with compression, ater 2 mins of cranking it starts and idles rough. What is the cause ??

Does anybody out there know of a workshop manual for the Astra H 1.7 Z17DTH. The Haynes manual only goes up to '08 and Every CD manual on the net wont run on Windows 8 64-bit. Anyone got any ideas?? Matt
