Well, changed the O2 sensors (pre cat), successfully.
Pretty easy. I would say easier than the Spark Plugs.....less steps. BUT, it didn give me a little scare when I got to the back one. It wouldn't tighten,...I might have been cross treading it. So I hand tightened it as straight as I could, and surely enough, got it right after the 3rd time. Car seems to run a little better, a little smoother. I think the weather would give you a good idea if the mix is right because of the new O2 sensors (it's around 38 F right now).
HOWEVER. Check engine light has not shut off. As I drove home on the freeway, I said "if it doesn't turn off by the time I get home,....then my battle is not over" .Surely enough, it didn't. So, I'm not exactly sure where to go from here.
I read that sometimes, for some fixes, it takes a couple of "cycles" to read that what it read as faulty earlier is not faulty anymore. So, I'm sure I can wait. OR, I could go to Autozone and have them check with the OBDII and clear the code.
Any other genius ideas?
