a few months ago I noticed a whistle noise when accellerating very quickly. Visually everything looks fine. Could this be a sensor, vacuum line or center head gasket???? Please provide assistance.

It Could be a bad pcv valve - pull yours out, clean, check or replace ($4)
I've heard this on a Gtp before

thanks so much. I have replaced the PCVrecently since this whistle noise started, so the old one was not the issue either. Hopefully you have another suggestion. Appreciate it.

Pull the pcv and make sure it has an o ring on the bottom of it. And that the top is sealed.

Flip your DIC to the "boost gauge". You seeing boost when you accelerate? It's time for all 2004 vacuum connections to dry rot. If this is the case, check the rubber "T" under the supercharger snout connected to the lower intake manifold.
