Gas cap is tight. I got the code pulled by Auto Zone and Monroe and they both indicated the code is stating that the CAT isn't working efficiently. I noticed from reading that a lot of times it is the O2 sensors that cause this. I want to look into replacing the O2 sensor's first (cheaper option).
Can someone tell me which sensors I would need to buy? They stated it is on Bank 1 ( passenger side) I believe. Also, is this the problem more frequently than a bad cat? Thanks in advance.
