Re: orbII codes 2500HD
po141 = HO2S Heater Circuit Sensor2 Heated oxygen sensors use time to tell if working or not eng not reaching temp fast enuff may set this or bad sensor.
PO161 = ? PO300 = Engine missfire detected PO440 = EVAP system fail can be caused by leaving the gas cap lose or a leak in the system good luck I dont see any one thing to cause all these at the same time.
