hi, Just got a Lupo 1.4 S and I have started to notice that on some occasions, particulary towrds the end of longuish journey,that the engine seems to cut whenever I seem to change down to 1st gear. When I depress the clutch in preparation to changing to 1 st, the rpm drops to below 500 rpm and dies on me. Don't think its the battery as it starts up fine and I don't think it's driver error but just wondering if any of you guys experienced the same and what you think the diagnosis is?
