Hey guys i am installing new Oxygen sensors on my 97 Integra and searched the forum and found a post that told me their are 2 of them on the bottom of the car. (One on Header) (One after/on Cat) i know the one of header is called Position 1 and the Cat position 2 but where the hell is position 3? I was about to get some NGK OEM Sensors and i saw a position 3 and started freaking out. Can someone tell me where this last sensor is? Thanks, Brian

 

There are only two sensors. On your LS, there is one in the collector of the header and the other is in the cat after the catalytic element.

 

It was referring to other cars that have 4 O2 sensors. Which are usually V shapped engines.

 

Ok sweet thats what i thought, just wanted to make sure i didn't have more then 2 of them. Thanks guys.

 

Ok i did them yesterday took me about a hour. Would of been easier if they had been replaced BEFORE 123,700 miles, they were original ones. OMG i can say they are a BIT** to get out!!! Or else it would of taken me about 20-30 minutes, was really ez overall. Now just to replace my Fuel Filter just found it its original filter to.. No wonder why my car has felt a little hesitant.. I would be grumpy as hell to if i still had my fuel filter after 10 years..
