Hesitation or Stall at Very Low Speeds
SYMPTOM
The vehicle may hesitate or possibly stall during very light acceleration when the throttle is opened gradually at extremely low speeds (walking speed). The engine can be immediately restarted. Recurrence is very rare because it requires a unique combination of driving mode, ambient conditions, and gasoline characteristics to exist simultaneously. A customer may describe only experiencing the symptom one time.
PROBABLE CAUSE
A PCM malfunction.
CORRECTIVE ACTION
Replace the PCM with an updated unit.
