Stumbling Ford

Some 2013 Ford F-150 trucks built on or before Sept. 18, 2012, and equipped with a 3.5L gasoline turbocharged direct injection (GTDI) Ecoboost engine may exhibit an intermittent stumble and/or misfire on hard acceleration after an extended drive at highway speeds during high humid or damp conditions.

This could result in a steady or flashing MIL, with DTCs P0300, P0304, and/or P0306, primarily for misfire. DTC P0430 may also be present.

Ensure that all hard fault powertrain DTCs are addressed prior to performing the following procedure.

Check for DTC P0430. If this code is present, replace the left-hand catalytic converter. If this code is not present, install a new charge air cooler (CAC).
