New O2 sensors

I have an '06 GT 'Vert I bought brand new, ordered from factory.
Anyway, she has 172K miles on the clock. Last year or so I noticed the idle was a bit rough, not bad, but rough. I did all the normal things, new air filter, cleaned the throttle body and MAF sensor, checked the plugs (they were fine), Ran a bottle of Techron through. Finally, I thought, with that many miles, maybe I should change the O2 sensors. I changed them and by gosh I think the idle IS smoother. I also think the mileage is up just a bit. Happy dance!

With 172k miles, I'm actually surprised the original 02 sensors lasted as long as they did lol.
