i have a 2001 M3 and its surging between 1500rpms and 5500 rpms im not sure if you can call it a surge because its almost like the car losses fuel every 750 rpms and it causes the car to jerk back and forth when you are accelarating its worse int he mornin if the car is parked out side but comes back throughout the day and then goes away. you cant see a noticable change in rpms when it jerks but you can feel a loss in power and then a jump back in power ive taken it back two time to diffrent dealers and the first reprogrammd the DME and then changed the TPS sensor. does any one have any idea what this could be
thanks
