Message: I asked this question awhile back but got no replies. Every once in awhile I get a whistling noise from the engine, especially on the hiway. Others have asked this question before and I was wondering if anybody figured it out yet. I've been to the dealer twice with it but of course it never happens when I want it to. It's a 3.9 with intake but the noise was there before the intake was installed. Thanks for any help.
