Forgive me for not having the exact code, I'll get that next time I go
past auto zone.  Last time though it was a slow response from the
upstream 02 sensor.  I replaced it.  Light is still on, code was the
same.

What else can I look at?  I typically do my own work.. but I'm not
quite experienced enough for troubleshooting this.  And all I've ever
heard about taking emissions troubles to someone are nightmares.  My
father spent $700 on crap before his light went off.  He fought and got
some of his money back but I don't need the stress.

Car seems to be running fine.  I failed emissions though due to this
and the fact that the check engine light was burnt out! (ok, it had
been on for a little while).  I can't renew my registration in June
unless I can pass emissions.  I'm seriously sick of dropping money on
this fine example of poor egnineering.  (transmisson, rear pinions, etc
etc etc)

All that said.. if I am forced to bring this to someone, should I bring
it to a dealer?  I've had bad experiences with dealers.. but if they
are best suited to this kind of thing, I'd force myself.
