O2 Sensors 97 TJ
Can anybody tell me how many O2 sensors my TJ came stock with. I am assuming its one up stream and one down stream but I'm not sure.

That 1999-2000 guide is a bit different than how his 97's 02 sensors are. There are two 02 sensors total with the upstream sensor being mounted on the lower part of the exhaust header. The downstream sensor is screwed into the catalytic converter. The downstream sensor rarely causes problem, it's the upstream sensor that affects the air-fuel mixture and can make the engine run badly.
