15 RAV4 what is the problem with high idle speed? Ask the great gods for guidance.

Hot cars are also recommended to clean the throttle and initialize. As long as the water temperature is normal, everything else is fine. No problem. The car is cold in the morning or when parking for a long time, and the engine water temperature can't reach the normal temperature. The mixture supplied by the engine computer is thick, and the oil supply is too small to meet the lubrication requirements, so the speed is high, the sound is loud or the work is unstable, and the tail smell is strong.
