BEEP WHEN LETTING OFF GAS

1991 Dodge Dynasty

Noises problem
1991 Dodge Dynasty 6 cyl Front Wheel Drive Automatic 150 + miles

There is a random beep that varies in how long it lasts also. I hear it when I am already up to speed and let off the gas, usually going down hill. It is not loud, like an alarm, so I really don't know if it is an alarm or some air/vacuum sound.

There are no warning lights or guage problems at any time. Any ideas would be great.

As an update, I think it must be a vacuum problem since when I run the air conditioner the air will blow out from the heater and defrost vents when I go up a hill and will return to the main vents when traveling smoothly.

Any ideas of where I should look for the problem would be appreciated.
