Dealers!
Good thing you didn't pay $500 for nothing!

Many auto parts stores (dunnow 'bout Napa - ask!) will rent you an OBD
code reader, or read the codes for free in the parking lot. (It's a 2
minute job.)

Check the lead wires near the O2 sensor. I don't know about the Civic
in particular, but in general the O2 wires are in a hot, harh area and
can get beat up.

Did the O2 wiring connector connector go on right? Check both plugs for
grease, oil, goop, etc.
