seconds, starts, may misfire after starting, then clears and operates normally for the duration of the drive cycle.

The PCM calibration may not be maximized for hot restart.

The PCM may have experienced an internal fault.
Correction

Review SI for the symptoms and conditions described above. Refer to Diagnostic Trouble Code (DTC) List - Vehicle.

-
Use a multiple diagnostic interface (MDI) for reprogramming and ensure that it is updated with the latest software version.
