INFINITI QX56 engine runs rough, won't exceed 40 mph, and has a strong gasoline odor on INFINITI QX56

Some INFINITI QX56 owners report experiencing rough engine performance, difficulty exceeding 40 mph, and a strong gasoline odor. These issues may be attributed to vacuum leaks, which can lead to poor engine performance and rough idling. Additionally, problems within the fuel system, such as fuel delivery or quality issues, can cause engine stalling and contribute to the gasoline smell. Ignition problems, including faulty spark plugs or ignition coils, are also reported to cause rough idling and hinder acceleration. To mitigate these concerns, owners are advised to inspect for vacuum leaks, check the fuel system for delivery issues, and examine the ignition system for any damaged components. Furthermore, a strong gasoline odor should be addressed immediately, as it poses a potential safety hazard, and seeking professional assistance is recommended for proper diagnosis and repair.
