strange noise on startup
After swapping from 4.6 to 5.4 when I start it sometimes it makes a sort of churpping noise that is coming from the intake (K&N CAI system) anywhere from 1 to 5 churps any ideas on what this can be? Seems worse after its wormed up never when its cold. almost makes me think it has something to do with vaccumn system.
