i parked my 940 up the other night (seemed to be running fine) came to it the day after and it will not start, it try's to fire abit and sometimes seems like its almost running on 1 cylinder, i have tryed everything i can think of but no luck. want to plug it into the diagnostics but i believe you cannot do it with a normal scanner? i believe it has to be a certain volvo one? just wondered if anyone can tell me exactly what i need to buy? or send me links to what i need? or if anyone has any ideas why it wont run?

cheers
