The dealership wanted 500 dollars to replace my oxygen sensor (they never should have even touched my car but it was there for a recall). The real mechanics wanted 300 dollars.
My friend Murph showed me that it’s possible to do a “big” job (read: expensive job) like this on your own.
Part from Rockauto.com = $52 after shipping
Special o2 sensor removal socket from Auto Zone = free rental with $30 deposit
Anti-seize compound = $1.50
Tutorial on popularmechanics.com = free
It took two minutes to remove the old one, ten minutes to rewire the new one to the connector, and two minutes to install it.
