basically had this problem the other day, golf vr6 took a long time to start in the cold the other day and when it did fire up it was a bit spluttery, but after a minute or so it was running perfect. it was -8 at the time though! also yesterday i stalled the car after driving it for about a minute, and again took a lot of cranking to get it running again! but most times in the cold it starts fine!! :-) any ideas?
