Hi Muhibur. Thanks for sending your question today. This could be either a vacuum leak or an issue with the ECU that is causing this high RPM issue. The only way to know for sure is to have a professional mechanic complete an engine idle speed is high inspection. You can click that link to learn more about the inspection.
