First I haven't a clue about an "ISUZU Sidekick" and have never heard of one. I own many SUZUKI Sidekicks and suspect that is what you have.
There are two different engines in 1996 Sidekicks. If you have a 16L 16 valve motor, it will say "16 Valve" right on top the motor. On the Idle Air Control (IAC) is kind of under the upper side of the curve of the intake manifold. It has both coolant lines (2) and a hose for metered air coming from the cast aluminium tube just down stream of the maf sensor.
If you have Sidekick SPORT with a J18 (1.8L double cam motor) the IAC is pretty much on top the throttle body.
The IAC assembly, mounted on the right side of the throttle body, controls bypass air around the throttle plate. By extending or retracting a conical valve, a controlled amount of air can move around the throttle plate. If engine speed (rpm) is too low, more air is diverted around the throttle plate to increase engine speed.
During idle, the proper position of the IAC valve is calculated by the ECM based on battery voltage, coolant temperature, engine load and engine speed. If the engine speed drops below a specified rate with the throttle plate closed, the ECM will then calculate a new valve position.
On 1.6L engines, four different possible designs of the IAC conical valve may be used on these engines. The first design utilizes a single taper shape, while the second design uses a dual taper shape. The third design uses a blunt-tipped valve, whereas the fourth design uses a rotating shutter. Care should be taken to ensure use of the proper design when service replacement is necessary.,,,

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.

Follow the air intake tube (by the air filter ) back towards the motor and you will see an aluminum piece inline with the tube and it should be located on the right hand side of the device. It looks black with 3 wires comming off of it.
If this helps you please accept the solution or send a reply for more information.
Thanks,
Josh
