I replaced the Idle Speed Control Actuator as a part of troubleshooting a rough idle. I took pictures for this DIY.

The Idle Speed Control Actuator, also known as the Idle air bypass, or the Intake Air Controller is a variable valve used by the engine control unit to match actual engine speed to target engine speed. it has the ability to fully open, fully close or anywhere inbetween. It sits at 1/4 open without power. The IAC will idle your car up while A/C is on, or while you are moving your vehicle. It also is responsible for "floating" your engine RPMs when you are letting your engine decelerate.
