hi,
I have this strange whining sound on 4.0L non-HO ('90) coming from area behind TB. It doesn't sound like mechanical sound, as it doesn't change with rpms. Sounds more like air or something coming in or out. Pitch changes slightly when i give it throttle, but quickly goes to standard.
The sound starts as soon as engine start warming up.
Anyone had similar experience ? Is this common on 4.0L ?
The sound is pretty loud, so I can hear it from inside also, but not too loud (if I turn on the radio, I can't hear this whining sound anymore).
Thanks
