1986 Supra, auto, 165000 miles
Trying to figure out what this noise maybe. It occurs at around 1900 rpm with speed 48-50 mph, foot on accelerator. Sounds like your blowing over the top of a bottle. At higher or lower speeds there is no humming.
If I take foot off accelerator, noise stops.
If I place car in neutral, noise stops.
Noise is intermittent. Somedays its humming, other days nothing. Occurs both when car hot or cold. Humming is very loud. Seems to originate from center of engine/car.
Any ideas?
Thanks
