Common Symptoms of the PCM Issue:- Vehicle hesitates or surges at low speeds.
- Engine performance feels uneven after starting in cold conditions.
- Possible illumination of the check engine light.
- Reprogramming the PCM: Updating the PCM software to the latest version can resolve these issues. Ford service bulletins often address these problems and recommend specific software updates to optimize performance.
