I have had 2 coils that stooped working on my car this season. I use supersparks and boost 2.0 bar on high boost and 1,2 bar on low boost.
About 2 months ago i got a new coil from Superspark. But this week I had another one stopped working.
It seems o happen when i'm under high boost.
I dailydrive 70% with low boost and 30% with high boost. When all was working fine I was able to boost 29 psi the whole day with no problems. When it happened last time I was pulling 3rd gear, no problems then shifted to 4th and when it hit boost it start to misfire badly.
After this I can't boost at all without missfire, even on low boost. Idles perfect though, even with the "bad" coil still in car.
I need to know what can cause the coils to stop working. Can I link the boost pressure and the coils malfunction?
Sorry for bad english...
