Check fuses, and the resistor block in the duct next to the fan.

That's normal. The EGR light comes on every 60,000 miles via a timer in the speedometer. You plug/unplug that wire combination to make it go away after you have "checked" the operation of the EGR system :rolleyes:

Yes, the flapper valves are vacuum operated. The air noise you hear is the vacuum actuators.
