this is a very newb question...I did a search with no luck. I am assuming we have two O2 sensors correct? One before the cats and one after. I went to autozone to get new O2 sensors because I just bought the car and I want everything in tip top shape. They could not tell me how many I had! I looked under the car and only observed two of them. Did I miss any others.
thanks

That's half right. There are two cats....so that makes for four sensors. Each exhaust manifold has two, one before and one after the cat like you said.

2 o2's 1 before and 1 after the cat. to a grand total of 4.
