consciousmechanic Posted December 1, 2010 Report Share Posted December 1, 2010 I have a 1998 Eldo Sport Classic Edition W/4.6L Northstar. The intake makes a very annoying high pitched whistle at high vacuum (it stops during the opening of throttle body) Is this a common occurence and what is required to fix it? No engine codes, but occasional rough running and stumbling. I can't find anything obvious, but I suspect an intake leak, and I would like some insight before tearing into it. Any info would be much appreciated. John Link to comment Share on other sites More sharing options...
