Idle Speed on '03 GT

My '03 GT idles at about 1200rpms, which seems a little high to me. It has a KN Typhoon intake on it that the previous owner installed, not sure if that would do anything. Does it/can it be adjusted to be lower? What should it idle at?

Are you driving around with your air conditioning or defroster on,that will bump up idle speed(does turning on your air/defrost raise your idle?).You can't manually adjust it without throwing a cel light.If you have a smooth idle I'd leave it.

No AC or defroster....not even running the fan usually. It idles very smooth and is pretty consistent at 1200rpm. I guess I'll just leave it. I'll have to try turning on the AC next time I'm in it to see what that does to the idle speed.

Just see if it makes a difference.If it doesn't then your IAC valve is either stuck open a bit or being sent the wrong signal.
