The throttle body on an engine houses the throttle, which controls the amount of fuel that enters the engine. It controls the engine's ability to maintain an idle, prevents stalling, and aids in acceleration. If the throttle body is dirty, it can cause problems with the engine running properly. During a standard service, sludge and carbon buildup out of the throttle body and off the throttle blade. The vehicle's computer is then hooked up to a special machine for an idle relearn procedure.

Check inside throttle body...the throttle plate could be dirty (especially around the edges). Carefully clean with a "sensor safe" throttle body cleaner. Don't let dirty fluid run down into the air passage to the IAC. (It's the small hole just before the butterfly). May want to plug that with a cloth before you start cleaning.
