Automatic zero position calibration . Automatic dim function . High-intensity LED lamps . Red emitting needle pointer . Exclusive meter stand . Narrow-band air/fuel ratio gauges operate based on the voltage readings given by the O2 Sensor that is mounted along the exhaust path of the engine. Voltage readings indicate a lean (not enough fuel) condition to a rich (too much fuel) condition. An engine running lean will cause the engine to run hotter and potentially damage engine components or the engine itself. An engine running rich can indicate problems as well. Running extremely rich can potentially flood the engine and cause it to stall. . . .
