Hi, thanks for writing in. Yes the O2 sensor can cause the vehicle to run lean. What the O2 sensor does is read the amount of air entering the engine and sends that information to the computer, the computer reads this information and determines how much fuel the engine needs. If you would consider, YourMechanic can send a certified technician to you to troubleshoot this issue and service your oxygen sensor as necessary. Thank You!
