Definitely clean out the throttle body, but probably not the whole problem.
Also check that your throttle position switch is clicking just off idle and has continuity across center to one of the outer terminals (other outer terminal should have continuity at wide open throttle). Check that your throttle dashpot is not preventing full throttle closure, sometimes they hang up and will act as an artifically high idle stop and also prevent the AIC from switching on.
Lastly check all your vacuum hoses and connections again. If you have a propane torch, you can "spray" propane all around the intake system, including fuel injectors and intake manifold gasket to find any vacuum leaks. The engine will noticeably speed up when the propane finds the leak and gets sucked into the intake. do not give up, you will succeed.
