325es surging in cold weather
i have a 1986 325es. right now it doesnt idle smooth. it revs from about 600 to 1200 rpm while its in park and running. my old 1987 325is did it too. but just recently, the has started to do it going down the road before it warms up. unless i put the pedal to the floor, the motor barely revs up at all. after about 10 mins of driving it works fine. it also seems to shift fairly hard during this time too. cars a automatic.
from a stop, i pushed the pedal in a quarter of the way and the car runs great. once i get around 20 mph and pedal halfway, it just quits reving up and almost like it stalls. but if i put the pedal to the floor the car launches off great. thought maybe it was transmission but that wouldnt keep the motor from reving up.
