You either need to adjust your linkage so it will allow the throttle to close all the way or you have an air leak....Check the linkage first, you can back out on the idle screw but if the linkage is not allowing the carb slide to follow it you won't see a change.

Start with taking the air filter off so you can see what's happening in the carburetor. Turn the electronics on but do not start the engine. Check that the linkage allows it open when you pull the throttle,closes when you release it and does not close more when you apply the brakes Normal idle gap is around 1-1.5mm. The knobs on the radio trim the servos,one for steering, one for throttle. You normally use the throttle trim to open the carb slightly more for cold starting then turn it back down once it is running and warmed up.
If the linkage isn't smooth,hangs up or doesn't allow full movement,adjust accordingly.

sounds to me like you may have a shot clutch, same thing happened to me. i wore down the clutch enough to where the spring broke and it completely removed my cars ability to idle
