I didn't, and you're right. In Tennessee we don't have emissions tests or inspections, but there's a chance I might be headed west to AZ or (gasp!) CA. If I do, it'll unfortunately need to be repaired. @beno, Can these parts be sourced for less?
I only took it to a dealership because I'm in a pinch for time and I tried several places that said they couldn't read the codes since it was so old so I just said "**** it" and dropped it off at Wolfchase Toyota.
Complicating matters is the fact that I travel for a living and live in an apartment, so I have nowhere do do any work myself and less than no time to do it. LOL :/
Not all areas in Az need emissions. I live in Pinal county and they are not needed.
