It could be, but I would prefer to not spend 1 k refitting the original coil set up, on a car I am getting a 2k trade in on. The C34 has had the wasted spark set up over five years and runs great. The car still runs great! The new coil pack and ECU reset has made it run even better! But the engine light issue is only a year old, and as I said goes away when I hit the dash. The only success I have had in keeping it off is by messing around with the wiring behind the dash. Hence why I believe there is so thing lose back there that is causing the engine to short on and off. Or that's the theory today.
