what happens if you dont replace a bad O2 sensor? i need to do mine, but haven't and now I get kind of a throaty sound and loss of power. I assume it's because the computer can't adjjust because it's not getting data from the sensor. I also hope I'm right and this problem goes away when I put new ones in.
Also, what's the difference (listed on SOR) between regular O2 sensors and "U" sensors?
