There is a coolant sensor that detects engine temperature and when cold will command more fuel to keep it running until normal temperature is reached. If it is not working correctly it will cause this condition. If you have a scan tool you can monitor this sensor.
Also, the throttle body has a plate that gets carboned up over time. It needs to be cleaned periodically. You need to remove the hose to the throttle body and use a cleaner on the plate and the body itself.
If you can, try these procedures and report back to us with your results.
