Clear Flood Mode


A flooded engine should be cleared by fully depressing the accelerator pedal, which causes the ECM to pulse injectors at a rate of 25.5:1. The ECM will maintain this injector rate as long as throttle is wide open and engine speed is less than approximately 600 RPM. When throttle position becomes less than 80%, the ECM returns to the ``starting'' mode.
