INFINITI G35 idle issues with power loss and gas smell, possible fuel filter problem on INFINITI G35

Some Infiniti G35 owners report experiencing idle issues accompanied by power loss and a gas smell. These problems may stem from a bad MAF sensor or a marginal evap purge valve, leading to rough idling without clear indications of a problem. Additionally, cleaning the throttle bodies on 2007 and 2008 models can inadvertently increase airflow, affecting idle due to changes in throttle plate positions. If idle issues persist after cleaning, some owners find it necessary to check the fuel pump, fuel pressure, ignition system, and valve timing. A misfire in a specific cylinder, such as cylinder 5, can also contribute to a choppy throttle response and trigger a check engine light. Moreover, replacing components like the MAF sensor and throttle body may result in surging idle, characterized by fluctuating idle speeds. Lastly, some owners may overlook the separate fuel filter, which can be accessed by removing the fuel bucket, and addressing it is crucial for troubleshooting fuel system-related idle problems in the Infiniti G35.
