I have been getting the moosing noise on cold mornings and it usually goes away when the engine has been good and warm for a while. It hasn't stalled on me yet, but I want to get this fixed before that happens. I ordered a new EGR valve, but they didn't send a gasket with it. I would think for 85 bucks you would get one, but my fault for not remembering to ask. The FAQ here also mentions a tube assembly? Do I need this tube assembly or is it recommended? If I do need it, I will order it tomorrow along with a gasket. Thanks for any help.
