1999 ford ranger o2 sensors
Hey, I drive a 1999 Ranger XLT (4.0L 4wd)
Been taking the hands-on approach to maintenance, so far so good, but my o2 sensor(s) have gone bad and not sure where to approach. Autozone/advance said i have two, but i've noticed that i have three (i'm pretty sure it's 2 up 1 down). My diagnostic code (as long as the dude read it to me correctly) said it was bank 1 and bank 2 o2 sensors that are bad. Which of mine are bad or do i need to get my code re-checked?
