Autozone doesn't lend out O2 OBD readers any more
Does anyone here know where I can borrow one? I'm in the SoCal area.
I'm taking a wild guess that my car O2 sensor is busted since driving my 98 Civic EX w/ 120K miles seems fine in SoCal 405 traffic jam it's only been 2 days since the check engine light was on. I wonder if this will significantly screw up my mpg of 29-31mpg.
What do you guys think?
