Ford Freestar chugging and stalling issue when in gear on Ford Freestar

Some Ford Freestar owners report experiencing chugging and stalling issues while the vehicle is in gear, which may be attributed to several potential causes. These include defective torque converters and worn-out splines in the transmission, leading to stalling, as noted in recalls for some models. Additionally, transmission slipping can contribute to these problems, making regular maintenance and fluid checks essential. Some owners find that replacing the camshaft sensor gear and shaft may resolve engine stalling issues. Furthermore, it is advised to check the electrical system for shorts, even if the battery, alternator, and starter appear to be functioning properly. Problems with the Idle Air Control (IAC) or Gear Selector Switch Sensor can also cause stalling when the vehicle is engaged in gear. Proper diagnosis and repair by a qualified mechanic are crucial for addressing these concerns effectively.
