hello all,
has anybody had a chirping (and I swear it sounds like a bird chirp) come from the engine compartment. It almost sounds like its the turbo ....it spools up and then releases some pressure ??? It only happens when the air tempurature is above 40 degrees F. It never does this when its below 40. When I'm on the highway and it does this you can feel a slight hesitation on the truck as well. It's driving me crazy.

Any help on this is much appreciated.
Max
