Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

One thing you can try is to take some carb cleaner and a soft cloth and give the throttle body a good cleaning. after doing so then you will need to perform the idle speed relearn procedure. I have enclosed the steps in the link below, copy and paste the link to your browser to open and view them.

This fast idle has happened since new and goes away once engine is warmed up some, problem goes away before reaching normal operation temperature
