I have a 99 mercury mountaineer 5.0 v8 and its making a loud humming noise when driving at speeds of 35-60 mph. Noise starts of low then gets louder at 40-55 mph unless I let go of gas pedal then it just goes away until I start to apply it again but doesnt get louder if I apply the passing gear just stays the same until like I said I let go of the pedal which I think is wierd but cannot figure out what that noise is. What do u think it could be?
have the same problem?
