Vacuum leak can cause it, header leak before the 02's can cause it. Faulty or dirty IAC can cause it, dirty Throttle body can cause it... A few more things but thats the most common.

Id say most likely, take your TB off, and take the coolant pasage thingy off the bottom and clean out your IAC passages
