I just got a P2004 & P2008 on my 2008 Fusion with 90K, checked the two actuator solenoids on top of the Intake Manifold, the right one is for the IMRC and sends vacuum to the actuator below the throttle body.
I checked the vacuum hoses and they hold vac.ok, you can test the hose going to the actuator by vac.it yourself and if you can see the lever moving and no leaks it probably is ok
next unpluged the pigtail from the right side solenoid and used a voltmeter on the pigtail and the meter reads 12V with the engine at idle, connect it again and checked solenoid operation - but there is no vacuum getting through the solenoid to the actuator below, so it's gotta be bad
Ford wants big $$$$ for that part so I looked in fleabay and searched for 9J559 and found it for $7 so I ordered both.
