Why does my car sound loud on a cold start?
When it is cold, more fuel is added to the air/fuel mixture to make up for the lack of natural vaporisation. So the AFR (air-fuel ratio) is seen by the ECU to be leaner than usual (below the Stoichiometric ratio of 14.7:1) so it compensates for this with extra fuel to make up for the unburned fuel due to the cold.
