Idle speeds are all controlled by the throttle blade position and a small motor called an IAC motor, it may need to be cleaned, you can test the system for fault codes when the throttle body is serviced. I hope that cleaning up the throttle body may be all it needs, has it been tuned up lately? The air filter being clogged can do this. Ok
