I have a 2000 Ford Ranger, 2wd 3.0L V6 with 143k miles. The CEL has been on for at least last 70k and I finally went to AutoZone and got the code read. Turns out the O2 sensor is bad and the EGR valve is stuck. Is that the kind of thing that I can fix myself? I don’t want to put a whole lot of money in this truck seeing as it has a lot of miles and has been running reasonably well, if inefficiently (21 mpg all highway), for so long. I have an ok tool set and I do my brakes, but I recently paid $70 to have the fuel filter replaced-I’ve done it before and I didn’t want to do it again. The truck is going back to my parents to be semi-retired and put into “farm use” so I wouldn’t mind fixing it up a little before giving it back but I don’t want to spend a lot.
