Every once in a while (I mean maybe once a month) my SES light will come on when I am driving slow (~30 mph) after driving for a little while. I finally grabbed a code for it today and it gave me 45, which is the O2 sensor - rich exhaust.

Since this rarely comes on, is it anything to worry about? And what is the first thing to try, maybe replace the O2 sensor? Thanks for the help.

The most likely cause of a code 45 is leaking injector or two. It's not uncommon for these cars, especially as the injectors get old with lots of miles on them.

Anytime anything breaks it will set an 02 code LOL.
