Jaguar XE rough idle issue on Jaguar XE

Some Jaguar XE owners report experiencing rough idle issues due to several common factors, including vacuum leaks, spark plug problems, or ignition coil failures. Symptoms associated with a failing ignition coil may include the check engine light activating, poor engine performance or stalling, increased emissions, reduced fuel economy, and difficulty starting the vehicle. Additionally, some owners note that vibrations at idle speeds can be caused by faulty engine mounts, which is a known issue in certain Jaguar XE models. Reports of stuttering during constant throttle, rough idling, and erratic rev counter behavior have also been linked to rough idle problems. In some instances, lightly tapping the accelerator has temporarily alleviated the rough idle, suggesting potential underlying issues with the engine or fuel delivery system. It is important for owners experiencing these symptoms to diagnose and address the problem promptly.
