I too have a 2001 forester (just a few months out of warranty) and for the second time in the last 5,000 miles the O2 (front) sensor is beginning to deteriorate. I have taken it to the dealer thinking this part would be covered by extended warranty, no such luck. I am fairly adept at wrenching, but am clueless about replacing this thing myself. I read the earlier post desribing where to locate the sensor, and I have to admit, it is not abundantly clear where and what I should be looking for. Would the person who posted the ealier message asking a similar question please tell me if they were successful in replacing this part. As well, does any know of a manual, or set of instructions I can get my hands on to help out with this.
Any direction is appreciated.
Thanks - Ryan
