i have a 08 750i that has lost all the low end power and is backfiring through the tb on the rear cylinder. it will not go over 32 mph and the 4x4 light is blinking from 2wd to 4wd but im sure the actuator is out on the front end because it still turns all 4 when it is in 2wd.
could the rear cylinder not be firing but every now and then and making it run like that. it will not idle either.
