Don't have high expectations that replacing that sensor will resolve your issues. That is a lean code and highly unlikely caused by a defective sensor.
What else do you think it could be? I will tell you what it is doing, When it is idling the car will vibrate,makes a sputtering sound,and has low acceleration speed.
The code merely indicates that the sensor is reporting a lean mixture. It's rarely the sensor to blame but things need to be tested to find out. Make sure you don't have any vacuum leaks anywhere or leaks in the intake snorkel.
My vehicle just recently had to have the A/C Compressor fixed and the Serpentine Belt replaced, Do you think something might not be connected right? Because the mechanic said they had to remove a lot of things to get to the A/C Compressor. Just started to have these issues after those things got replaced. Or do you have have other ideas on what could be wrong?
I would recommend testing the o2 sensors ability to read rich and lean running conditions . To test it you will need a scanner or a scope. This is something that might be best done @ a diag shop.
