RPM Fluctuation when driving on cruise control


Topic starter

Hi Scotty, 

I recently bought a 2018 Acura RDX base with 60,000 miles. I've had it for a couple of months and the car has been great except that when I drive with cruise control on the highway at 70 MPH the RPM's will fluctuate.  I've occasionally noticed this while idling as well.  

How do you suggest I fix this? 


Thank you,
