Could be a bad IAC valve.

It's probably one of the 2 relays against the firewall near the battery. Mine died a painful intermittent death. When it finally went out for good the car wouldn't hold an idle at all and set a code. The relays are all of $15 from the dealer and they're both the same relay. I *think* it's the inboard one (but not 100% certain on that as it's been over a year since I changed mine out). No idle or start problems since. ~Juliet
