Ford Taurus rough idling issue after camshaft synchronizer replacement on Ford Taurus

Some Ford Taurus owners report experiencing rough idling issues after replacing the camshaft synchronizer. These problems may arise if the check engine light is on, indicating the need to check for OBD II codes that can help identify the specific cause. Additionally, owners should inspect the air filter and vacuum hoses for any blockages or leaks, which can contribute to rough idling. Ensuring the cam synchronizer was installed correctly is also crucial, as improper installation can lead to timing issues. If rough idling persists, some owners find it necessary to replace the camshaft position sensor along with the synchronizer housing for effective resolution. Proper timing adjustment for the cam synchronizer and related components is essential, although it can be challenging without specialized tools. While rough idling may not cause immediate damage, it is important to address the issue promptly, as unresolved problems with the cam synchronizer can lead to gear failures and potential engine damage.
