    1999 S10 Blazer 4x4 LQ4 Started Missing on the the way home.

    My blazer started missing on the way home and threw a p0174 code and p0300. I noticed my o2 sensor reading odd on the bank 2 (passenger side I assume). The log file is attached. Everything is stock on it except some of the trans settings. Thanks for the help guys. I appreciate it.

    Well, I think I may have an O2 sensor dying on me on the passenger side. My plugs looked perfect on the driver's side, but all 4 on the passenger side were covered in black soot. Thanks for looking guys.
