Running rough this morning, now engine light flashing ?
Quick google search saw could be severe multiple misfires , anything I should check first ? Is it bad or a cause of wheeling as I just ran it pretty good Saturday? Thanks

P1491 Rad Fan Control Relay Circuit An open or shorted condition detected in the radiator fan control relay control circuit. This includes PWM solid state relays.
P0304 (M) CYLINDER #4 MISFIRE Misfire detected in cylinder #4.
P0161 (M) 2/2 O2 Sensor Heater Failure Oxygen sensor heater element malfunction.
P0158 (M) 2/2 O2 Sensor Shorted To Voltage Oxygen sensor input voltage maintained above normal operating range.
P0455 (M) Evap Leak Monitor Large Leak Detected A large leak has been detected in the evaporative system.
I'd start checking the O2 sensor fuses and wiring first.
