Chirping noise?

[BigDiesel]

When I'm putting along under light throttle and I let off, sometimes I get a slight chirp from the engine bay somewhere. Once in a while it will do it when I get back on the pedal lightly. It doesn't do it if I hammer the pedal, just under very light throttle. Thanks

I notice a very similar sound.I havent worried about it as I have put alot of miles on it since I bought it two years ago.Not under full throttle ,as you said.

My truck makes a chirping noise when idling hot. I'm guessing it's a belt driven issue or motor mount. It chirps when you shut it off hot, when the engine comes to a stop. not a belt squeek though. it's done it forever now without consequnce.
