Hi Car_talk guys,
Two weeks ago my 07 Kia Sportage starts running funny while im driving to work. I stopped at AutoZone as soon as I had the issue come up and it reported that I had a heated oxygen sensor that was failing bank 2 sensor 1. So im able to drive it sputtering on and off till i was able to park it at home and order the parts.
I ended up replacing both downstream heated 02 sensors, since I read I should replace them in pairs. this would be ultimately what I did. so I take it for a drive and it still sputtering, I reset the ecu by pulling ecu fuses and turning car to on for five minutes as well as disconecting the battery after. Still im having the same issue no codes are presented anymore, but still plenty of sputtering when accelerating. I have both upstream sensors to replace as well but I was going to wait to replace them because of how the sensors are in such a tight spot. At this point im considering replacing those two upstream sensors but I’ve got all kinds of different ideas being thrown at me from family members from spark plugs to spark plug wires need to be replaced and I’m just not sure a this point what could be doing this?
