I own a sapphire RS Cosworth 4wd converted to 2wd. I had an issue with my magnecor ht leads R100
Firstly I had misfire when boost was higher than 1,3 bar at 5000rpm and upwards.
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?
