Rough Idle on Startup

After leaving Tractor Supply earlier this evening, my engine had a rough idle as soon as I started it. I also did not hold it to start as long as I normally do. It only lasted for about ten seconds or so, but it was taching at about 200-300 rpms (usual is about 800). Any ideas about what this could be?

Are the symptoms the same with both cold, and hot start?

Daniel, my patron!

It only happened once, so I guess I shouldn't be worrying about it, I haven't been able to recreate the problem either. The engine was warm at the time. Any simple things I could possibly do to help prevent it from happening again?

I was thinking it might be the IAC so I just got out of the garage here at the rescue squad after cleaning out the throttle body and spraying down the IAC. I must say, I thought my vehicle ran smoothly before, but I had no idea it was possible for a vehicle to run this smoothly. I also just ran in half a bottle of Seafoam into the vacuum line and put the other half in the gas tank. I am now letting it soak in. I can't wait to see how it runs!

Thank you for your help,
