INFINITI Q45 intermittent stalling issue after refueling when stopping at a light on INFINITI Q45

Some INFINITI Q45 owners report experiencing intermittent stalling issues after refueling and when stopping at a light. These stalling problems may be linked to several factors, including the need for regular maintenance and timely replacement of purge solenoids to prevent fuel system failures. Additionally, some owners encounter vapor lock issues that can disrupt fuel flow, causing hesitation and stalling shortly after refueling. An underlying problem with the idle control system, such as a dirty throttle body or Idle Air Control Valve-Auxiliary Air Control valve (IACV-AAC), may also contribute to these stalling incidents. If cleaning these components does not resolve the issue, some owners find it necessary to test the mass air flow sensor, which may require replacement if faulty. To effectively address these concerns, it is advisable for owners to maintain the fuel system, investigate vapor lock issues, and check idle control system components. Further diagnostics on the mass air flow sensor may be needed if problems persist.
