Hi all...the engine light on my 1998 forester just turned on. I think it may be the oxygen sensor or pcv valve. The owners manual doesn't address these components and I am wondering if anybody out there knows how to identify the location of the O2 sensors and pcv valve and how easy it is for a backyard mechanic to replase...the local auto parts store has the parts but I want to make sure I kinda have a clue before I buy them and end up in a weekend of misery...any advise would truly be appreciated on locations and installations! Thanks in advanced!
