Ok, I need a little help because I'm clueless.
Should I have an O2 sensor in the exhaust manifold and one after the cat?
I have a feeling I'm missing an O2 sensor.. the car is running rich and I'm failing emissions. I'm not saying that it's the only problem. But, one of the codes it's throwing out is a rear O2 sensor. I had a mechanic look at my car today and he said it looked like an O2 was missing.
If I do have one missing, Midas is going to hear an earful from me.
