Sorry to say, but Sears and Firestone have an extremely bad reputation.
don't do that again.

They didn't use OEM, that's 100% certain.

What? What exactly what did they sell you and why? On the surface, this
sounds like a bumpf-type excuse to boost your bill.

Bad decision on two counts: 1) Leaving it for a month. 2) Bringing it to
Firestone. I would have brought it in as soon as I could have spared the
time, or less than a week.

That is correct. The MIL can illuminate with a number of O2 sensor
errors.

It is unlikely (but not impossible...) that the oxygen sensor error had
to do with the valve adjustment.

Do you know the EXACT alphanumeric numeric code that was recorded? This
is critical. Most O2 sensor failures these days have to do with the
heater circuit. If it does not say on your invoice/work order, call the
dealer and ASK. They OWE it to you if you ask.
