Hi guys new here, I have a 98 vt berlina and having trouble when it is cold. For eg: I start the car an warm up for 2min then i take off down the road and come to a set of lights 100m from home and it starts to idle lumpy and rough. But when i take of again and stop another 500m away it is gone. It will idle fine when warm to please help if anyone has or who have known of this problam thank you!!
