More information needed here I think so just some guesswork follows. If a hot engine is left idling after a run,the temperature guage will rise due to heat rising from all the hot components and no ram air through the engine compartment,the electric fan will cut in and out(is this the "revving"you hear). If your engine is running hot when driving along,it is most likely the thermostat is stuck in closed position,this needs rapid attention or engine damage can result.Check coolant level when cold and if you have to drive it,keep the heater set hot to increase the amount of coolant in circulation.

Your car is overheating when idle because there may be a lack of oil or water in the engine. It can also be a problem with the engine itself. If your car is overheating, simply contact a wrecker or a road assistance company. The police are also available to assist you.

you have to turn the idle screw down ?? ? ? ? ? ? ? ? ? ? there are 2 of them. one on the right and one on the left. the left one is general idle and the one on the right is for air-conditioning idle and high power output idle ( rev higher ) A vacuum line may have come off if it has started revving.

The idle speed on modern computer controlled vehicles is not adjustable. If you are having idle problems you will need to take the car to a mechanic.

Try changing or cleaning out the stepper motor, this controls the idle and is a common fault on the 306.

The icv is located next to the rev cable.

your sunfire is revving if the idle is set to high, or when adjusted. the idle is high also when the engine needs to warm up in cold weather. there is also the possibility that the engine temp sensor needs to be replaced, for it is not relaying proper heat temp. the light on your dash may show you engine temp, check this. if unable to do this yourself, you may need your cars manual.

No! it only controls the air/fuel mixture at idle - it is by-passed when the engine revs-up. Generally, when there is a problem with the air control valve it causes the idle to become erratic and 'hunt' and maybe the engine keeps stalling.

No revving your engine dosent damage it.

If it is not overheating then the temp gage or the sending unit are bad.

Either the idle is adjusted to high or the cam on the choke is stuck in the closed position

No, it wouldn't affect the idle unless you were somehow overheating the engine.

I'm going to guess yo have the air on, that would mean that the idle compensator is out of adjustment and over revving the engine.

Increasing the rpm (revolutions per minute) would be revving the engine.

The word revving is a verb. It is the present participle of the verb rev.
