I have been chasing a similar prob on 86 9KT . Started happening only at high speed . Then I found I could "milk it" by gently increasing and decreasing the throttle . When I connected a press/vac gauge to the intake manifold I found it was only happening at high boost which leads me to suspect the "Hooter Valve" . I have a "High Press." one on order. This will be my 3rd . The standard ones do not last I have read . To prove the problem I have wondered about putting the weak one on backwards so the high pressure side is not trying to compress the spring .It would still open by the vacuum from the manifold but chickened fearing damage to the compressor blades .Perhaps you are more courageous ?
