I have a loud humming noise coming from the filter of my K&N FIPK which I installed less then a week ago. After reading other threads I think it my be the IAC valve, but before I replaced it I was wondering would a bad IAC cause wierd idle or will it just cause that annoying high pitched humming noise from the filter? My idle doesn't fluctuate it stays pretty steady, so would the IAC valve be the culprit? I have 53000 miles and never cleaned or changed the IAC valve so maybe its time too. Is there a gasket I have to get for the IAC if I get a new one or does it come with everything I need to replace it when I buy it from Ford.
