TY Peter. I may need to find E3 earth point that may be in the 'Tunnel', tho I have no idea where thiis may be. So am going to Take out instument panel and make my own earth
I had the very same problems and went through the change coil pack , change crank shaft sensor. The problem was caused by my putting diesel into the petrol tank. Once I drained it and put fresh petrol in problem solved.
