Hi all. As noted in my intro post, I recently bought a 2003 ZR5 CC that I'm loving!
Yesterday, I had the Cat Converter replaced after chasing codes all over the place. SES light is off
and she has more power! 126K miles.
As it is a new-to-me, I would like to get certain things squared away so that I have a base point for future ref. I've replaced plugs and wires, cap, and checked rotor. All good. I have found some deteriorated vacuum lines that will be replaced this weekend. I would like info on how to identify if my O2 sensors are stock. Is there a way to tell?
Previous owner obviously took great care of the truck but kept no service records.
Pics will come soon. We have a bunch of white junk all over that just won't seem to go away. It makes a mess of a Black truck.
