Hello, there are various inputs that influence idle speed. Idle air control valve, temperature measurement, emissions controls, fuel delivery, fuel trims -- this all needs to be checked and monitored in a diagnostic process. Not just replacement of components. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
