If no check engine light, I would start by removing the throttle body and give it a thorough cleaning. Remove the IAC and clean that as well.

Idle Air Control Valve. The guy in the video points it out very early in the video. He probably said Idle Air Control Valve instead of IAC. Sorry for the confusion.
