 F30 335I 2013 Second log the car stuttered the most and that's when the driver malfunction light came on again car was perfectly fine before this and could accelerate in comfort and sport mode all day to the floor but with tune its limited. Also to note whenever I turn the car off the misfire corrects itself in a way and the driver malfunction goes away and it drives fine again but once I floor it to the ground again it pops back up very co fused and I put in brand new coilpacks and spark plugs Bosch oem before the tune |
