Nissan TITAN won't restart after idling, experiences surging and backfiring issues on Nissan TITAN

Some Nissan TITAN owners report experiencing issues such as not restarting after idling, surging, and backfiring. Surging during idling may be linked to engine misfires, vacuum leaks, or spark plug failures, while backfiring can stem from a faulty ignition system, fuel system issues, or timing problems. To address surging, owners are advised to check for misfiring and vacuum leaks, and to inspect spark plug conditions, often seeking repair estimates from certified shops. Backfiring may require a thorough inspection of the ignition and fuel systems, as well as timing. Additionally, some owners encounter rough idling due to missing cylinders, which may resolve upon restarting the engine, while others experience stuttering or stalling, particularly with the VQ35HR engine. Regular maintenance, including spark plug checks and ensuring proper airflow, is recommended to prevent these issues. If problems persist, consulting a certified mechanic or dealership for accurate diagnosis and repairs is advisable to ensure optimal performance and safety.
