The SES light was illuminated on the Saturn @ 114k, so I retrieved the code, which was a P0133. This indicated a slow response from the upstream oxygen sensor, so I replaced it with a Bosch "OE style" unit for $64.99 from AutoZone.
While the car runs significantly better now (more peppy, much smoother, no more gas odor during idle), I'm rather concerned about the white deposits that were present on the old sensor. I'm afraid that I have another condition going on, and it may kill the new sensor as well. Here's a picture of the old sensor, and I would appreciate it if someone could tell me what these white deposits are from.
Thanks!
