VWVW 1 Posted January 16, 2011 Could be the sound coming from ISV damper box... Mine is deleted and it make the whistling sound under load not sure if yours is still present. Quote Share this post Link to post Share on other sites
jakegti 0 Posted January 16, 2011 is that the box opposite the throttle body with a metal plate under it? Quote Share this post Link to post Share on other sites
VWVW 1 Posted January 16, 2011 see second pic from another thread I have found...The black box arrowed I think thats the ISV Damper viewtopic.php?f=1&t=54565&hilit=isv+damper+pic Here is a bit more info I found about it from other threads The plastic box near the throttle body connected to the ISV on OBD1 VR6 motors is the ISV damper. It keeps the ISV a little quiter. Without it you might hear a slight whistle, whine, or airflowing past the ISV when the ISV is in use. Quote Share this post Link to post Share on other sites
