Hard to give a definite answer to that one....not enough information. Generally, high idles are caused by either a sticking Idle Air Control valve or a vacuum leak allowing air in somewhere it shouldn't be. Look at the condition of the hoses connected to your engine's intake and replace any that are cracked or split. Also make sure the intake air duct from the air cleaner to the intake is intact. Hope this helps!
The IAC valve is just that...The Idle Air Control Valve. It is responsible for keeping the idle at set parameters. And yes, it can make the engine idle at high RPM.

A typical idle speed for a normal car engine is 600 rpm to 1,000 rpm. It is higher for buses and motorcycles. RPM stands for revolutions per minute.
It maintains engine idle rpm when the throttle is closed.
750 rpm
when the engine starts and is warming up the idle is supposed to be at around 1500 rpm but when the engine warms up the idle should drop to between 700 and 1000 rpm. if it doesnt drop then see a mechanic because it is a very complicated fix
The usual idle RPM for a diesel engine typically ranges between 600 to 800 RPM, depending on the engine design and application. In some heavy-duty diesel engines, the idle speed may be set slightly higher, around 900 RPM, to ensure proper lubrication and cooling. It's essential to consult the manufacturer's specifications for the exact idle RPM for a specific engine model.
normally idle around 1000rpm
when u first start the car it will idle high, around 1.5 rpm to 2 rpm. when its warm up it should idle between 700-1000 rpm
It is intentional, it is called high idle. It helps warm the engine to proper operating temperature.
About 600 RPM
maybe you need your computer reflashed. It worked for me.
