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.There was one common cause for the type of high idle concern you are describing and Acura released a service bulletin that calls for replacing a broken evap canister control diaphragm, I have enclosed the bulletin in the link bleow, copy and paste the link to your browser to open and view it. Have a look and see if this is the problem you are having.https://dl.dropboxusercontent.com/u/104923897/Fast%20Idle%20Nov%2028.pdf
