Noraml as the engine needs to work harder to run the compressor
An A/C compressor takes about 6 horsepower to turn it and when an engine is idleing, it is producing about 30 hp so when you take away 6 hp from 30, it puts quite a load on it. There is also a device which increases the idle speed when the A/C is switched on. If this is not working or the idle is set too low then rough idle may occur.
The fast idle-speed on a 1994 Nissan D21 pickup is adjusted by turning the screw on the side of the throttle body. It increases the speed of the engine when the vehicle is idle before completely warming up.

It is normal for the RPM to increase a little when put in park or neutral. If the RPM increases by a lot, then you need to adjust your idle speed.
To change the idle speed in a Honda, you typically need to locate the idle adjustment screw on the throttle body, which may require removing a cover or accessing the engine bay. Turning the screw clockwise increases the idle speed, while turning it counterclockwise decreases it. It's important to make incremental adjustments and check the idle speed with a tachometer to ensure it meets the manufacturer's specifications. Always consult the vehicle's service manual for specific instructions related to your model.
AC idle compensator. Many vehicles have a sensor that increases idle speed when you turn on & add more load. Sounds like your idle not being adjusted. Have your mech check it.
Does not have one. Idle speed is controlled electronically through an idle speed control module.
To adjust the idle speed on a 1997 Jaguar XJ6, first ensure the engine is at normal operating temperature. Locate the idle speed adjustment screw on the throttle body; turning it clockwise increases idle speed, while counterclockwise decreases it. Use a tachometer to monitor the RPM and adjust to the manufacturer-recommended idle speed, typically around 700-800 RPM. After adjustments, clear any diagnostic trouble codes if present, and ensure the throttle response is smooth.

aint that the icv it regulates air at idle when the throttle body is closed this stops dips in revs or stalling when foot is off the accelerator and on the brake it lets an amount of air to bypass the closed throttle valve to keep a steady idle rev speed of engine it also works when a heavy load is placed on engine at idle / closed throttle heavy load usually being radiator fan coming on at temperature also aircon switched on although the cars ecu may have an inbuilt raised idle speed for when aircon is switched on.
