Hey everyone, I am having an issue with my 08 and it seems to be unintentionally accelerating when I am in the 55-65 MPH range and let off the gas. It is not every time and no codes are being thrown. Also I am hearing a slight whine noise under the hood upon acceleration. I believe that is a tension pulley, but I am not the best with vehicles so I was looking for some opinions. First post so be easy! Thanks for your help.
