  • our O2 sensors

    I have heard that we have 2 O2 sensors, 1 before the cat and 1 after the cat, and I have also heard that we have 3 O2 sensors, 1 per manifold and 1 after the cat. which one of these descriptions is correct, or are both of these wrong? also, I hear we have narrow band O2's. Can we just switch to wideband O2's and be able to run an Air/Fuel gauge to it to measure the A/F ratio, or do we need to get a Wideband O2 kit to swap the whole Narrow band system to a wideband system so the computer works correctly? This is really confusing me and I'd really like clarification on all this. This would be for a 2001 Firebird.

    3 O2 sensors....1 in each manifold/header and one after the cat....the one after the cat is to make sure that the cat is working.

      Thanks. Now, do we have narrow band O2 sensors or Wideband O2 sensors? Also, if we have narrow band O2's, then can I just swap in a Wideband O2 sensor in their places and have the computer still be able to read them, or would I have to get a kit for them to work?

        My 96 has 4 O2 sensors. One in each manifold, one before the cat, and one after the cat.
