Hello,
It sounds like you might have an issue with the Idle air control valve.
Many times if the IAC valve is dirty it can have an impact on the idle of the engine.
You can take the valve off and clean it. Usually that takes care of the issue.
Here are couple of helpful articles on how to clean the valve:

It will also be a good idea to clean out the Mass air flow sensor.
As when it gets dirty it will impact the drivability as well.

I have attached the diagrams for IAC valve and Mass air flow sensor.
Please let me know of any questions.
Thank you.
