    OBD-II Code Engine may stall is defined as a Throttle/Fuel Inhibit Circuit High

    The Fuel Injector Control Module (FICM) monitors engine speed in relation to the power requested by the driver. If the engine speed gets higher than requested by the engine computer (PCM), the FICM will disable fuel going into the engine, causing the engine to shut off. Code P2555 will be stored. Additional codes may also be present and should be diagnosed and repaired first.
