Whistling sound on deceleration

[TexasJ10]

On my way home from 243's I noticed a whistling sound when I would decelerate from about 65 mph to around 45 mph. If i pushed the gas pedel even a little it would go away. It was loudest at the greatest mph and decreased as I slowed down. I checked all the vacuum hoses when I got home and couldn't find anything. It seems to run fine. Has anyone else ever had something like this happen?

The only whistling noise I've dealt with was a leaking/tired vac booster on the brakes. Has the pedal feel/pressure changed at all recently? Sorry just a wild a** guess but my first suspect would be a vac leak too but I know at 65mph I wouldn't hear it anyway. :(

I had a very loud whistle on deceleration and idle on my chero. It would go away as soon as I hit the gas. I suspected a vascuum leak but could never find the problem. When I replaced the carburetor my problem dissappeared. You may want to start there.

as suggested it's probably a vacuum leak

And I always thought that that was wind noise. smile.gif

Mud Thrasher. That is what I thought at first but I only had to barely push teh accelerator down and it went away. IT is raining right now, but I think I will check teh suggestions above and see what I can see. The brakes haven't been great, but theyy have never been that great anyway. I have had the carb hold down nuts loosen over time. It will be interesting to see what is causing it.

I have a whistling sound on a ford at just the right theottle position, from an open element air cleaner. Do you have an open air cleaner??

[TexasJ10]

It's the stock air cleaner and even has the hose to the front still attached. I checked it and it is tight to the carb as well.

could it be some sort of exhaust leak?
