My car, during cold starts idles like a pig. It runs really rough and hesitates. Once the engine temp is normal and the oil temp is at 70-80 on the guage the car runs fine. Is this rough idle/hesitation on cold starts normal on the m3 or is there something wrong with the intake/fuelling/idle control? Need advise I do not want to be ripped of by my friendly BMW dealer.
thx a lot
