I recently installed the BMS dual cone intake and the JB3 2.0. For the last five days my car has been misfiring when idle. I have been reading a couple threads and it seems to me like I am not the only one with this problem. I scanned the car with the BT tool and got these codes :

MSD80/MSD81 Engine module for N54

Sounds like either plugs and/or hpfp.
