I'd bet five dollars against a stale donut you will find someone with the same problem in the past.

Vacuum leak is first on my mind perhaps intake something or (reply)

another. I'll check the canister & hoses. I get the noise at the RPMs mentioned but since the noise is there either at opened or closed throttle I was thinking drive accessory or such. Need to gather some leak detection stuff, perhaps a short piece of water hose, & watch & listen....if I can get Barbara to run the controls. She worked in the clean conditions of the Operating Room so long she's not big on dirt......not that my firewood/woods bumming truck would be dirty.

If it's power steering noise it will.... (reply)

not a high probability but I had a small hole in a vacuum canister that made a high pitch whistle just like you describe. other than that drive shaft bearings.

Change in sound as you move the steering wheel left and right.

I'll check that, normally a Ford weak spot.

I'm thinking power steering pump fluid is low or the pump itself is feeling it's age

IIRC, the idle air control motor will start whistling under some condition and I have totally forgotten why. It's been forever since I've seen this. Seen it happen on the crown Vic's with the 4.6 also. If you haven't resolved it by Monday shoot me an email at sixgun 452 at yahoo dot com and remind me and I'll dig around and see what I can come up with. Also, just for grins, check your PCV hoses and fresh air intake duct work for vacuum leaks. It's very common for Ford vacuum hoses to deteriorate and suck holes in them and also very common for folks to leave the PCV vent side hose that plugs into the fresh air intake hose off.

Check your vacuum lines for leaks or cracks

Nothing specific, but if engine speed has no effect, that leaves the running gear, or air around the body. If it changes in close relation to the vehicle speed, then I would suspect running gear, hubs, drive shaft, or tranny and transfer case. Last resort, make sure the vent windows are closed all the way.

accessories, ac, pwr str, alt, serpentine belt idler pulley, smog pump. A really long screw driver and the human ear is an amazing old school diagnostic tool. Could be a bearing beginning to squeal. As always "actual results may vary".

Whistle

1994 Ranger, 4X4, 2.3L, 5 speed manual. Getting a whistle, perhaps a high pitch whine beginning at 2500 RPM & seems to mostly quit about 3200 RPM. Throttle open or closed, same sound. Any advice where to begin? Thanks guys & God Bless.
