Hi everybody I am new to this site. Any advice would be appreciated on the stated problem. I have a 3.0L Legacy Lancaster 6 GT 2001 model. Exactly a year ago the engine light came on, I got it diagnosed and it was one of the pre-cat o2 sensors, so I got it replaced. Light off, no problem - until a few days ago.
Same story, light came on and has stayed on ever since, but the car is running sweet. I know that there is a raft of different possibilities as to what it could be, but what I'd like to know is if there is anyone else with the same vehicle that has had the same/similar problem? If so, do you have any advice or tips on solving the problem or what to look for first? Thanks in advance.
