Drivers side front o2 sensor. If you've been running the car hard, disconnect your battery for 15 minutes or so. Reconnect it and the code probably will not come back. Mine came on at the drag strip, and hasn't come back since I reset the computer. It may run shitty for a couple of minutes or possibly a couple of drives, but once it relearns its fueling, it'll be fine.

You're welcome lol I recognized that code and I have the printout from autozone that says what it is sitting right next to me lol. Good luck. hopefully you won't have to replace them.
