Fix for Low idle speed — Ford Fusion, Mercury Milan
These 2006-07 vehicles with the 2.3L engines may exhibit low idle speed and late transmission upshifts. You won’t find any trouble codes related to this problem by scanning the PCM. Don’t waste your time trying to clean the idle air control valve. This is a software glitch and you must have the PCM flashed with updated software.
