Ok, I was driving home today after dropping my husband off at work, and
midway home, the check engine light came on. I went to Auto Zone, and
the guy there told me that the code meant that it was either a. my
catalytic converter or b. my muffler. How can I tell what it is? I
haven't noticed a whole lot of problems. We just had the timing belt
replaced on Labor Day, as well as the water pump. I haven't noticed any
decline in performance either. I'm not for sure if the guy was right or
not since he didn't look like he knew what he was doing.
