SOURCE: 02 sensor stuck lean on bank one
It is possible. What I would do is look at the O2 sensor data on the scan tool. If it is stuck lean than I would give the engine a couple shots of carb spray through the air tub. If the sensor switches to rich than I know the sensor is good and there is a high probability that there is a vacuum leak. If the sensor does not switch than I know the sensor is stuck lean and needs to be replaced. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!
