^i believe this is the code I got. I have a 2004 v6 5 spd bone stock. Code said o2 sensor stuck lean. And possibilitys were exhaust leak, misfire or fuel injection system badly out of calibration. I had an exhaust leak on my 00 and it doesn't sound like I have one on this car. And I don't think it's a misfire because the car runs great but does feel like it idles a little rough. Anyone have any ideas on what this could be or anyone have this code before??
