(T) Cutting Out

Good Morning

got a slight problem with the seicento, its a 1.1 sporting v reg, the problem is the car has started to cut out when driving but it only seems to do this when the motor is cold, say in the first 10mins of driving after that it runs fine, also when it does cut out it will restart fine straight away


do you reckon it might be a sensor or sumin,

cheers
