Hi - this could be a problem with the idle control valve, either dirty or failing. Leaking fuel injectors, clogged air filter, or low fuel pressure might also cause the symptoms you have noticed.

I would recommend having a certified mechanic, such as one from YourMechanic, complete an inspection to determine why the car idle is rough and suggest any needed repairs.
