Why Is Rpm High When Car Starts. High rpm readings might occur while your car is idling, or during acceleration or driving at a constant speed, with each scenario potentially pointing to different underlying causes. On the car with the idle that was. A throttle body cleaning is likely to cure the high idle speed as well. On a carbureted engine, the fast idle screw sets the idle speed at a high rpm, like the name implies, to allow the vehicle to quickly warm up, while the choke is closed. Find out the common causes, such as. The higher idle allows the engine to run while the air fuel mixture and timing are less than optimal. It is normal for a car to rev high when starting, with the engine rpm going up to about 1200 to 1400 rpm and then gradually coming down. You can try cleaning it and see if that improves your idle speed. If the pcm offers no hints, the best place to begin looking for problems is with the idle air control valve/bypass air control (iacv/bac).
