Upstream oxygen sensor circuit slow response driver's side...Anyone have any ideas what can cause this? I checked the wires, they're in good shape. As far as removing the the sensor goes, I'm a little shaky on getting under there with a torch right next to the fuel lines to remove it. Anything I should check first?
