Scion FR-S stalling during turns with warning lights, computer tests show no issues on Scion FR-S

Some Scion FR-S owners report experiencing stalling during turns accompanied by warning lights, despite computer tests indicating no issues. These owners suggest that problems with the fuel system, such as a clogged fuel filter or failing fuel pump, may contribute to this stalling. Additionally, issues in the air intake system, like a dirty air filter or malfunctioning mass airflow sensor, have been noted as potential causes. Faulty ignition components, including spark plugs or ignition coils, could also be responsible for the stalling. Some owners suspect that a faulty Engine Control Unit (ECU) might not trigger error codes during tests but could still lead to stalling. Furthermore, a vacuum leak, which may go undetected by computer diagnostics, is considered a possible factor. It is recommended that affected owners seek a thorough inspection by a qualified mechanic to accurately diagnose the stalling issue.
