Whenever my "check engine" light has come on around the 60k~70k mile mark,
I've found it's time to replace the O2 sensor. If the other fixes don't
help, you might try it. It's a $60 part needs to be changed about now
anyway.

FWIW, I've found that a smooth idle while warming up and otherwise
good power followd by **** poor stumbly idle is usually caused by
a "lazy" O2 sensor. Reason being the O2 sensor isn't used for warmup
just idle and cruise, and at cruise your engine is more forgiving
about the mix.

Try googleing on that subject and you find quite a few references.

I guess you are referring to the upstream o2 sensor. Where do you find one
for $60? Most everyone where I live want $80
