So, I finally got all of the exhaust done, put an O2 simulator on, and now after driving for a few weeks have an ses light with a P0140 code. Whatcha guys think? My car isn't running any different, so I assume it is the O2 simulator. If it was a fuel problem, or something else, wouldn't it be obvious? Any advice?
