Well Sicy, If your familiar with working on your own car I would first try this. Take the black plastic/rubber air intake tube off. Start the car up and take a bottle of carb cleaner and spray into the intake. You will have to manually rev the engine up to keep it from stalling. There is a spring mechanism on the side of the throttle body that moves. This is what you will want to push on to rev it up. Spray the throttle body really good. You will probably notice a lot of black exhaust while doing this. Sometimes this is all it takes to fix idle problems. If it keeps doing it then you may need to take the Idle Air Bypass off and clean it. That is the long cylinder shaped piece that bolts to the side of your throttle body. Take it off and clean that with carb cleaner also. You may need to let it sit for a while. After cleaning that place it back on. Unhooking the battery for 10 minutes while doign this might be a good thing. That way you reset the computer. If it keeps up then I would check for codes. It could be a number of things after that. Hope this helps
