Hello all. My bmw misfires. My mods were an afe intake and ecu reprogram.
After i find that my bmw misfires i return the car at stock options. Stock intake Stock ecu.
The car still misfires. I changed all my coils, my fuel injectors and my spark plugs and the car misfires again. Any ideas?

Get a obd2 reader and pull the codes, unless its not severe enough for the dme to register a fault.
