Well I am pretty sure mine is not fuel as I have tried Shell, Caltex,BP and Mobil and makes no difference. It does it when car has not been started for a few hours. The initial acceleration through the first few gears is hesitant but then all good. Maybe I will get Ford to plug it in the computer and see if its thrown a code. Car only has 3000kms and its done it from day one. And I dont believe the car needs to warm up when stationery for ages like the ol' Fords had to. Mine idles for 60secs,tops, in the morning and then I gently take off as most do. Thanks for the replies.
