I had my check engine light tested and I was told that my O1 and O2 sensors are out. I have located them in my truck but I am not sure how to change these out. What do the wires lead to and how hard are they to change? Mechanics charge a lot compared to the parts alone. I am good with the basics, ie. Brakes, Spark plugs, and such.
Should I try?
