ISSUE
Some 2008-2009 Taurus, Taurus-X, Sable and 2007-2009 Edge and MKX vehicles may exhibit a rough, rolling idle, or the idle speed dropping below specification. This condition typically occurs most often in hot ambient temperatures with the A/C on when idling for extended periods. Vehicles may also exhibit idle speed dropping below specification on light throttle application with vehicle cruise control engaged and traveling down a hill or a low speed tip in clunk.

ACTION
Reprogram the powertrain control module (PCM) to the latest calibration using IDS release 61.05 and higher. This new calibration is not included in the VCM 2009.5 DVD. Calibration files may also be obtained at the website.
