I got in my 09’ G37 Sedan after work today and the SEL light immediately turned on followed by a high idle ~1K rpm. It was cold and rainy idk if that has anything to do with it. I drove to AutoZone to pull codes which came up as P0305 (Cylinder 5 misfire) and C1109 (Battery Voltage (Abnormal)). Besides the high idle I didn’t notice any rough riding, no weird engine noise or loss of power and no weird smell. Any advice?
