IWhere is the idle air control valve on a 5 speed 97 vw jetta 2.0 speed?

The idle air control valve (IACV) on a 5-speed 1997 Volkswagen Jetta 2.0L engine is located on the intake manifold, just below the throttle body. It is usually held in place by two screws. The IACV is a small, cylindrical device with a plunger that extends into the intake manifold. It is responsible for controlling the amount of air that bypasses the throttle body when the engine is idling. This helps to maintain a steady idle speed and prevent the engine from stalling.

To access the IACV, you will need to remove the air intake hose from the throttle body. You can then use a wrench to loosen the two screws that hold the IACV in place. Be careful not to drop the screws into the intake manifold. Once the screws are removed, you can pull the IACV out of the intake manifold.

The IACV is a simple device, but it is important for the proper functioning of the engine. If you are experiencing idling problems, you should check the IACV to make sure that it is functioning properly.
