I have a cylinder one misfire and injector 1 misfire on my 2005 kia Sedona. I have replaced my plugs and wires, coils and injectors. I also changed my timing belt. The codes are under pending codes and I erase them and they come right back. The car runs like it has a dead cylinder,also its a 3.5
I'm kind of wondering if the o2 sensors being bad can have anything to do with that cylinder
p0031 o2s heater upstream-min
p0301 CYL.NO.1 Misfire detected
po201 Fuel INJ.NO.1 Circuit Mal.
it might take a minute I need to take the plenum off again
thankyou very much one of the wires broken to #1 injecter miss went away and cleared codes. we will use your service in the future.
