I held the button for 8 seconds after each to erase them but no luck.
What do these 3 codes mean together, what can I do to fix, and why won't they erase?
FYI: Wiring harness is an updated (circa 2002?) part.
Thanks in advance!

in my experience the check engine light is almost exclusively related to a failing 02 sensor which is an 80 dollar diy fix...
an easier way to confirm the 02 failure or impending failure is a 5-6 mpg drop.
