During cold start, the idling speed would be higher than standard of around 700 rpm at operating temperature.
Seems the idling speed is too hogh resulting in the vehicle wanting to move forward without the accelerator.
Check coolant level.
Check Idle Air Contral valve.
Check for vacuum leakages.
How much would depend on what is wrong.
