If anything, clean your ICV. but other than that, your idle fluctuation is perfectly normal. When you let your foot off the gas, the engine speed will obviously go down. The computer senses the dip in idle speed and adds fuel to stablize the idle. It's working exactly as intended. Stop worrying and enjoy your car. Trust me, you'll have real problems to ask us about down the road.
