Default 04 Mustang 3.8 V6 Idle speed

Hey all,
I have an 04 3.8 V6 mustang and I'm noticing the car idles pretty steadily between 800 and 1000 RPM even after the car is warmed up to normal operating temp. It just feels odd to me because all cars I've owned idel at about 500RPM when the engine is warmed up.

Another thing I notice is that the RPM gauge jumps to about 1500 when the A/C compressor kicks in for like 1 second and come back down to about 800.

I was wondering if anyone else with the same car had the same idle rates and the same behaviour when the A/C compressor comes one.

Any help is appreciated.

Thanks
