I have a loud humming noise coming from under the hood whenever it's in idle or reverse. Upon acceleration, the noise disappears but then comes back any time I come to a stop. Any ideas?

its a common problem on v6 cougars, its your iacv valve it is going bad. go onto www.newcougar.org and u will see a temp fix for it or buy a new iacv valve.
