Help quick 02 sensor question
I am replacing the o2 sensor on my 94 and there is a sensor on the left and the right exhaust pipe are they both o2 sensors? If they are the Haynes handbook says it is the left one, what is the right one? Snould I replace that one as well? Thanks in advance for your quick responces. :confused:

Yes, there are 3. 2 before and one after. The one after is so that the computer can know how well the cat is working. The two before measure the exhaust before it is converted.
