87 325e On cold start will consistently start and idle fine. Every start afterward, until it sits for about 4 hours or more, requires giving it some gas just to make it start then woking the gas to keep it running just for a few seconds then it will idle fine. Also there is a noticable surging( up and down) when accelerating, not a detectable miss but a gradual surging mostly noticable while going through the gears. Any ideas would be greatly appreciated.
