Unstable revolutions

Daewoo Lanos 2002
When starting the engine, it tends to stall. Once it warms up, it normalizes but, after a while, it starts accelerating and decelerating by itself; it does never reach a stable working. The fuel pump has been replaced, injectors cleaned and fuel filter, spark plugs, timing belt and even tensor checked, but the problem persists. Thanks for your help.

It might be the IAC valve. Check it and clean it; it is not hard at all.
