Later the same issue appeared when I simply raise boost higher than 0,2bar.
Finally I had misfire all the time except idle.
I believe that there must be something like a magnet field from magnecors and engine loom but I m not sure yet.
Has anybody ever had the same issue? Any solution?
Are you sure its the HT leads? Easy way to prove it is to stick another make of leads on to see if the misfire stops.
