2004 318i Cold Start Problem!
I have a 2004 318i (2L 4cyl). I've had it for about four months now and recently the cold starts in the mornings have been a little rough.
I stop and start all day and it starts fine its just the first 20-30seconds in the morning after the car has become dead cold it seems to drop in revs (around 400-500rpm) and sounds like its going to stall, the revs then go back up to 1000rpm and then runs smooth for the rest of the day.
I just changed the oil and oil filter two weeks ago and just changed the fuel filter yesterday.
Does anyone know what the problem is as I just want it to start normally every morning like it does during the day.
