Time to clean the throttle body. Do a search on throttle body cleaning or check on Youtube.

My 06 has a problem with water leaking into the #1 and #2 spark plug hole. Every once in a while I have to remove the coil and the plug, clean the coil boot and put it all back together. Only takes about 20 minutes, but it smooths out the idle everytime. Not saying that's your problem, but that's a problem I have.
