- 2004 explorer v8
I have a 2004 xlt explorer 4.6 2wd. Im desperate to help the gas mileage, im getting around 10 mpg city. I read around and think its best that i replace the 02 sensors as it has 170000 on it. I called autozone to get sensors and they dont have a clue as to how many i need...i know...so i called ford parts and they started talking upstream, downstream, bank 1, bank 2. Im not a mechanic but i know where they are just dont know about the upstream and bank thing. please help.. if i knew whick sensor was which then i think i could do it myself. I have 2 before the cc and 2 after ..
.. thanks to anyone who is willing to help
