94 excel X3

We have a 94 X3 that has trouble starting. Whether hot or cold if it doesn't start first time it can take up to an hour to get it to fire. There is plenty of spark, and when it does fire up it blows out smoke
that is almost pure fuel. It also flares the throtle up to about 3000 rpm when at a set of lights after the hard start. Have been told it isnt the airflow meter of the O2 sensor. also have a friend with the same car and his started doing it at about the same milage....220000kms

You should probably check your coolant temperature sensor. If it's reading too cold a temperature, the ECM will overenrichen the fuel mixture.
