I had problems for months. after talking to a fellow CEGer' he gave me this idea. 3 foot insulated hose (i used braded for looks) with 7/8 opening. this picture is self explanitory. this 3 dollar fix REALLY WORX!!!!After 6 months of humming and being annoyed daily i knew there had to be an easier way than buying a new one or cleaning the IAC. I also heard if you clean the IAC the moosing gets worse.....which makes sence...ah........hope this helps
