loud whistling rattle

[jjbharr401@msn.c]

hi all
have a loud whistling/rattle coming from the truck. it starts when i hover the accelerator at any speed above about 20 - hard acceleration it disappears and lay off accelerator it is gone but if i press accelerator half way it is defening and really winds you up. sounds as if its coming from either the front/ middle area
any ideas????

Sounds to me like the common IAC valve failure, but that normally happens at idle, and goes away with throttle.

Does it sound like that?

thanks for the replies - it sounds nothing like the video and is more like a really super loud squeeky wheel which seems to get faster as the engine does.

Could it have to do with a slipping belt? You could rule out the belt, and belt driven stuff by removing the serpentine belt and running the engine for a few minutes.

there also seems to be some vibration felt through the seats and steering wheel when hard accelerating.
can anyone are these rangers normally good runners or will i be pouring money at it constantly????????
