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.

The problem you are describing may be caused by a dirty and sticking IAC as well as sludge build up in the throttle body. Start first with making sure the throttle body is clean with no sludge build up as well as the IAC (idle air control ) valve. When doing the cleaning procedure be sure to remove the negative battery cable so the computer is cleared .
