Just changed spark plugs in my Saturn Vue 2006. It's the 4 cyc 2.2 L. noticed throttle body was pretty dirty. Sprayed Throttle body cleaner. Didn't remove from vechicle. Did the learn procedure for idle. Seems to run ok - but noticed a slight surge in rpm while driving, shifting a bit higher than normal. Also, shifted car into neutral while driving. RPM remains high, around 1500 and doesn't seem to come down, even when I brake. Could that mean the throttle body is still dirty? Was thinking about removing it from the vechicle and cleaning good. Also was thinking the MAF sensor or Intake Air sensor might be faulty. Looking for suggestions?
I would try the idle relearn procedure again, making sure everything is off while it idles- no radio, lights, a/c, etc.
Take it to a qualified repair shop , Thinking ??? Also was thinking the MAF sensor or Intake Air sensor might be faulty . TESTING IS THE WAY TO A PROPER FIX !!!!!

Pull the engine coolant temp sensor, I know it sounds funny but do it if your looking at the engine it is located on the right side of the head.. chances are the ceramic tip on the sensor is cracked.. 15 dollar fix or so should take away from the high idle.. let me know how it works

Try tighting up your intake throttle body there should be 2 10mm bolts where the intake hose attaches to the throttle body. I had this problem with my sons car 2002. It was an air intake leak. Be careful not to break the bolts. you my have to remove and reseal.

You might want to pull the coils and ignition control module. They are really easy to get to on this car, right on the front of the block. Ignition control modules can be tested electronically at most chain parts stores. Coil can be a bit more of a pain. Quite honestly it's very rare that any that I test, even the ones that I know are bad, test bad. Sometimes the coil windings spoil out and when they get hot they swell and no longer produce spark.
Is this a problem only in idle? Is it drivable and if so what happens then?

You could try replacing the idle air control valve but I would obtain one from a local salvage yard, its cheaper and you are not certain if thats the problem, another thing i would check is your intake manifold gasket where it meets the cylinder head, if tha gasket is cracked or leaking it will allow excess air to enter the engine and make it idle higher, the easiest way to verify this is get a can of carb and choke cleaner and spray it all around the intake gasket area, if the engines idling characteristics change drastically then the gasket is bad and needs to be replaced if theres no change in the idle I would start looking for vacumm leaks and the idle control valve issue, which you specified.
