[QUOTE="r stead, post: 1027958, member: 72412"] had a similar problem . when engine was idling , it roared . checked all the above suggestions . replaced IAC with no change. but when you raise the idle it would fade away. tried spraying brake cleaner around intake to check for leaks nothing . crawled underneath and felt exhaust gas coming from around nut on the EGR tube going to exhaust manifold it was loose . tighten it up the roar was history.
