MY TRUCK WHISTLES
Hello...
I am writing as a last resort by a tired and increasingly angry ranger owner. I have a 2003 Edge the 3.0 Liter V6 and somewhere over the last few months it has been making a loud whistling sound as soon as the truck reaches 2500 RPM.... Anything below or in Neutral, no whistle what so ever. I have been to three mechanics now who cannot pin point the problem, one guy says its the toss up between the throttle body butterfly valve and some other part, both costing $500 to fix but he cannot guarantee the choice so its like a 50/50 gamble. Another mechanic said it was some plastic tube that goes from the intake manifold to the throttle body housing, but the part was replaced and no fix... All mechanics have been saying they have never heard anything like it and even our local ford dealer told them they couldnt suggest a problem...
So as a last resort I really hope someone here has encountered the same problem, coz apart from this the truck is a beauty...
Thanks

Vac leak most likely. i think there is some stuff you can use to check for leaks. but thats really the only thing i could think could make it whistle. unless its one of those far out problems that i hear about every once and a while.
I.E.
Dude buys a F150, and every time he hits a bump he hears a squeaking/ rubbing sound in the rear. has tires checked, replaced, brakes, the whole 9 yards and nothing fixes the squeak, meantime the guy drives the truck for about 10k more miles, (patience of a saint) and finally gets hit in the bedside. it gets a new bedside and as the wrench turners are cutting whats left of this bedside off to replace it, a plastic Coke bottle falls out. it had been rubbing inside the bed since it came from the factory. some dumbass worker must have dropped it in there when the bed was being put together.
could be something like that. but probably not.

try taking the air filter and box apart, in a clean area and run it up to 2500rpms. No whistle its some where upstream still a whistle downstream. If you remove the intake hose at the throttlebody, I believe it will throw a code because no air across the MAF but it should let you know if its in the intake hose. It could be anything you just have to either be patient or sell it. Good luck keep looking.

my 3.0 does this too!!!! finally someone who has this problem. my truck has had this problem for a while now, it has gone away tho. i have an intake done up on the rig so i think it may be that but i know that these motors have been known for the air boxes being dirty with leaves and twigs n stuff. but i havent had mine whistle at me for a while. but take apart your intake and clean any carbon buildup in the throttle. that should do it. mine would do it at 2500 rpm with minor or major load, but not in neutral. so try to do a good job cleaning it and hope its not a vacuum leak. i know i am

My dads blazer did that after a new heater core was put in. It would only do it under load. Found out it was a vacuum hose that came disconnected from behind the dash for the heater controls. I figured it out cause whenever you stepped on it all the air from the heater went to the floor vents.

i've read on many ranger forums that there are bushings or bearings or something around the camshaft, or around camshaft position sensor that wear out and around 90,000 miles or so, depending on the truck, they can wear to the point to where it sounds like a belt squeal or a whistle, at certain rpms.
listening to the description, i dont think it is the cam but anything is possible.
