ISSUE
Some 2005-2006 Expedition/Navigators may exhibit a hard start during multiple restart attempts or during hot soak restart attempts and / or the malfunction indicator lamp (MIL) on with diagnostic trouble codes (DTCs) P0340, P0344, P0172, and / or P0175 and / or a reduction in power between 3500 and 4500 RPM during wide open throttle (WOT) application. Some customers may describe the condition as feeling like the transmission is slipping, a lack of transmission upshift or a hesitation. 2005-2006 Expedition (only) may also exhibit a higher than normal idle on cold start.

ACTION
Follow normal diagnostics for the vehicle symptom(s) to determine if there is an actual physical issue with the fuel / ignition / exhaust systems and / or base engine causing the symptom(s). If no issues are found during normal diagnostics and the symptoms still occur, reprogram the powertrain control module (PCM) to the latest calibration using IDS Release B43.4 or later. Calibration files may also be obtained at the website.
