I replaced an O2 sensor about 3 weeks ago in my 1999 GMC Yukon Denali, it was bank 1 sensor 2. Then today I got an error code saying that I had a cylinder 5 misfire. Any suggestions or previous experience with this problem? My scanner still shows that the O2 sensor has low voltage?? My main concern is the misfire. It spit and sputters when running and barely will move. My check engine light flashed repeatedly then stayed on too.
