Ok, im pissed, I looked all over. Where is my O2 sensor?

Its a 91 TA with 350 TPI from 89. It has SLP Y pipe with random tech. cats, SLP headers, Hooker aero chamber cb.

Where is it? Or atleast in what area?

um on your manifold...not sure which one...it would be just a one wire one I believe though...been a while since I had my 89 so I cant remember the exact location...probably not easy to find though on a tpi car to be completely honest.

So its on the actual header? I figured that it would be after the Y so that it would get a reading from both and not just 1 side.

Pretty sure you only have one o2. With SLP Headers the o2 is most likely towards the bottom of the passenger side header.

On the drivers side header just above the y-pipe flange... you cant really miss it!

Yeah I found it. Drivers side. Was a bitch to get out. Old one looked like "chalk". New AC Delco now installed. Lets see how it helps gas mileage.

Did you use an o2 sensor socket?

No lol...They make a 7/8ths extended deep well socket with a groove cut in it for the wire to come out of... makes life ALOT easier. ShlepBoys has 'em.

Open end works better on SLP's. You can't really fit an O2 socket on them.

7/8ths does the job right 8)

I told you where it was you douche, driver side header...Kinda hard to miss the big 4 inch metal sensor with a wire coming out, sticking out of the side of teh pipe!!
