As I was travelling home today this morning I was trying to think of what I did about 6 weeks when I first had the problem.
I replaced the main earth cable.. This is still new so couldn't of been that.
The only other thing I did was spray the engine with wd40 as I'm lazy and was on the way to a local cruise
So I thought this morning I wonder if that helped, so just before I left I soaked the dizzy and the leads.. Low and behold I drove 180 miles back to bristol car never missed a beat!
So no I'm back and have my tools I will most probably start with taking the dizzy cap off to check the arm and replace it. Then go on to the leads
as this has to be the problem
