Question about throttle body

I cleaned out my throttle body the other night (first time with my new car). Cleaned it with throttle body spray. It was pretty ugly. After cleaning it, it looked brand new. Got everything hooked back up (and yes, it's all properly hooked up), started her up and drove her around...An hour or so later i get a CEL. Take it to autozone to have it read and it throws something like "Idle air malfunction" or something like that. I triple checked to make sure all connectors/vac lines were on. Everything is fine, but i'm still getting the CEL. I never got it before i cleaned out the TB.
The book the guy looked at had a couple different reasons for that code. The 1st reason was "engine vacuum leak". 2nd was "Idle air control". and i can't remember the others.
Any ideas?

The IAC could have got some TB cleaner in it, and it could have made the sensor malfunction change it and see what happens.

yeah that's what happened to me once,

did you take it off to clean it? if so did you use a new gasket when you put it back? if not you probably have a vac leak
