I've seen posts on here where people are saying that there is only 1 02 sensor on the 240s. I have a 95 with 2 sensors on my exhaust. Are they both o2's or is only the before the cat an o2 sensor?

they are both o2's. having one before the cat and one after helps the computer decide how well the cat is working. i have a 1990 and it has only one on the end of the header, the posts you've seen are probobly people with an older model like me. then again maby im wrong....
