Ford F-150 Stumble

Some 2013 Ford F-150 trucks built on or before 9/18/2012 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 DTC P0300, P0304, P0305, P0306, primary for misfire. P0430 may also be present.

Ensure that all DTCs are addressed prior to performing the service procedure. If DTC P0430 is present, replace the left-hand catalytic converter. Refer to the workshop manual section 309-00. If DTC P0430 is not present, install a new charge air cooler (CAC). Refer to workshop manual section 303-12.
