Jb4 Misfire
One day with my new JB4 and cylinder 3 is dead. I had read that the jb4 was hard on plugs and coils but wow. 3 is dead on all maps. I'll switch out coil packs between cylinders tomorrow to check. Where to get coils on a Saturday.?

I have a set of oil coils if you need them Located in Melb Tbh I would ditch the JB4 and use the MHD tune Download it from app store on android phone or tablet JB4 is old tech and while some people are still running it without issue, MHD is safer, smoother and provides more features Let me know if you need the coils |

It is not the JB4 per se that is hard on plugs and coils, but the increased boost it provides.
