I have an 08 335xi stage 1 v10 mhd, i was getting misfires for bad injectors and i swapped them all out now im getting (29d0) cylinder 4 combustion misfire only on cold starts. I have swapped all the plugs coils and injectors and the car still misfires only in #4 and only when cold one warm it runs great its as if the injector is leaking but if i pull it before the car has started it is dry and looks fine, after about 45 seconds of running the car starts to misfire and plug is wet and very black i dont know what else to do , please help!
