I got a check engine light last week while driving. On
checking the code at our local Advance Auto he tells me that both Upstream O2 sensors were showing bad. At $200 plus each this is kind of making me wonder if there could be something else contributing. Is this normal for them to go out in pairs? If I replace them will the computer automatically reset and the light go out?
