Question about Cars & Trucks
I looked at info for 3.0L engine. You don't have an iac as such. You have tac/throttle actuator control. You don't have mechanical throttle cable from pedal to throttle body. It's done with wires and sensors. Any applicable trouble codes?

the most common causes are plug wire, plug, vacuum leak at intake, fuel injector failure and last no/low cylinder compressio.

The idle air control valve is located on the back of the throttle body. It has an oval electrical connector and two torx screws holding it in. Unplug the connector, remove the two screws then lightly tap the body with a soft faced mallet to loosen it from the body.
Once you have it out and prior to installing a new valve clean the seat inside the throttle body where the idle control fits. This must be very clean! Installation is in the reverse order.
To save some cash, pull the valve out and clean it with throttle body cleaner, this usually fixes the problem for quite a while.
Good luck and hope this helps.

SOURCE: 1993 Toyota Camry IAC cleaning
1) remove the black intake hose from the throttle body
2) get a can of throttle body/intake cleaner
3) be VERY careful if you decide to use the straw included with the can of cleaner, it can detach and go inside of your intake manifold.
4) spray inside and use a rag to remove junk from throttle plate(front and back side), hold the straw on the cleaner can and spray into the hole just ahead of the throttle plate, let soak for 10 minutes or so
5) reattach intake hose and start engine - you may get black smoke/rough idle for a minute as junk exits the engine

The Idle Air Control (IAC) valve adjusts the engine idle speed. The valve is located on the side of the throttle body. The valve is controlled by a duty cycle signal from the PCM and allows air to bypass the throttle plate in order to maintain the proper idle speed.
Do not attempt to clean the IAC valve. Carburetor tune-up cleaners or any type of solvent cleaners will damage the internal components of the valve.
