Humming Ford airbox?

Hello,

I have a '99 ford contour, v6, auto with about 86K miles on it. I have been getting an intermittent humming noise from the area of the airbox. It's hard to pinpoint since just opening the hood and poking around seems to quiet it down. It usually starts about 30 to 60 seconds after I start the car and is gone by the time the car warms up. I'm guessing it's an actuator in the airflow system that is trying to engage or disengage that is stuck or is not getting a good control signal. Anyone ever run into this that can give me some clues?

Thanks in advance, VI

I didn't know airboxes had any sort of actuators... Make sure your filter is clean. That being said, your most likely problem is the IAC in the intake. The sound will usually propagate down the intake and resonate when it finds resistance by the filter.

How does the IAC make sound?

You have the famous Contour intake "moose" There's a TSB and parts available to fix the problem. Hit up contour.org for details
