i have a 2004 infiniti i35. whenever the rpms pass somewhere between 925 and 975, it makes a chirping noise. we sent it in for warranty repair at infiniti. they changed the serpentine belts, but the chirping sound still exists. does anyone have a similar problem or know what the problem is? thanks.
