Hi everyone, I have a 94 318i with the 4 auto it starts fine but it seems like the cold start funtion stays on, and im getting a rich burn when warmed up. and also rough idle. any help would be great it's my first BMW, I have been a Volvo man for many many years, I look forward to getting her back in shape. I have herd she could get up to 40mpg. Thanks J Rogers.
