I have an extremely high pitch whistle while i am just at an idle

any part driven by the drive belt can do this

I had that , and it was the transmission low on oil. Hope this helps.

Transmission pump.

it may be a turbocharger if so equipted, lots of turbocharged cars whistle as the unit gets older..only other thing I can think of is something with the exhaust system.. get it looked at by putting the car up on a lift and inspecting it..now some cars also whistle thru the radio ..this is called alternator whine and is usually correected by a filter in the power line of the radio...good luck

mmmhhmmm there can be 2 problems #1- your pulleys need to be replaced or #2 u need new belts
hope this helps

you may have a tensioner or idler pulley starting to go bad. They make a high pitched whistle when the bearings are on thier way.

Simply have someone slowly bring it up to 2000 rpm and listen with the end of a wooden broom handle touching the center bolt on each. Be careful not to get caught.

If you're not used to this you may be able to hear it whithout use of the "hearing aid"

Your drive belt may simply need dressing. You can buy this at almost any auto parts store for about 4 bucks. (dont use anthing else as you will cause the belt to stretch creating more issues)

Sounds like a vacume leak, chk. for a cracked or broken vacume line or maybe one came off. Does it idle ruff? With it running open hood and listen for a low pitch whistle you may have to rev it up a little.

check all vacuum hoses,sounds like a leak, try spraying carb cleaner near noise,if engine rpms go up you found the leak

There may be a small hole or cut in a vacum line or possibly just loose. Also make sure the air filter box and the big hose to it are secure and clamps etc are tight. Pulleys and belts can make a high pitch sound also.

Check for a vac. leak. First listen for a whistle or a high pitch sound if you have any fix them. You can get a can of carburetor cleaner and spray around the vac, hoses even the big one on the brake booster unit and the back of the master cly.
