I am a little lost right now. I have a 1990 998cc Mini. My engine starts just fine and drives well but at time would have a hard time at idle and would start to cut out. It is common for at time to start cutting out and dying at junctions, traffic lights, roundabouts etc, having to restart many times, it then just have a hard time or not idle, though runs fine under load. I did have this problem in the past but went away on its own but now i think it is here to stay.
