Hello and thank you for using Just Answer. My name is ***** ***** I’d like to try and help. Based on your issue, I would disconnect the throttle position sensor and see if it stops. This is what usually causes this. The default rpms for Volvo with max rpm with no vehicle speed is 1500. I am sure this is your issue. I hope this helps. Thank you
