Apparently my o2 sensors are toast. I'm also not paying Gregs 600$ bucks for them to do a 10 minute install.
Bank 1 Sensor 1 and bank 2 sensor 2 are both done. I know these are precat.
However, I can't for the life of me find the second one. I've found one already, the one that is closest to the pipe coming down from the manifold, but don't know what bank it is. It really doesn't matter, since I'm replacing both. But could someone point out where the other one is?
