Help - Oxygen Sensors

Sicy Stang · 10-10-2003, 07:58 PM

Where are the oxygen sensors located on an 88 5.0?? I need to check to see if I have them. I'm going through hell right now because I need to sell my car and it has had a straight pipe on it for 8 years, I've gotten "hooked up" with smogs in the past but now I have to do it legit because of this new CA smog bullcrap.. so I have to put my original cats back on and I'm guessing I need 2 oxygen sensors.

My god, $50 each???!! If someone can tell me where exactly they're located (if I can even see them..) and maybe where I can get them for cheaper than $50 I'd be very appreciative.

Sicy Stang · 10-10-2003, 09:20 PM

Gah I think I posted this in the wrong forum ..

anyway I found some for $39.99 but that's the lowest I've seen.

joe4speed · 10-10-2003, 09:45 PM

They're easy to find, right above the bend towards your engine. Yup, you only need two, I believe the newer cars need to be HEGO(heated o2 sensors) but 88's were the regular ones, which is good, cuz they're cheaper!

Sicy Stang · 10-10-2003, 09:50 PM

Thanks for the reply. So are they connected to the engine or to the pipes or what?

I feel so dumb

They are connected to the pipes. you will see the bungs they thread into by the top cat.

Uhm.. well I have the original cats off of the car that I'm looking at now and there is only one like round hole of some sort sticking off one side of the pipe near the top cat. Then there's two like things sticking out but since I cant explain it here's a pic.

lx mike · 10-11-2003, 01:40 PM

those are the hangers. look up in front of the crossover pipe there and you should see 2 threaded holes, those are where the oxygen sensors go into

Sicy Stang · 10-11-2003, 01:56 PM

Ugh this is frustrating. I dont see any kind of threaded holes, just the tips of the pipe like in this picture... am I looking in the right place?

What is that round thing sticking out then in between the pips in the first picture? That's been cut, I dont know what it is.

Well I'm having it done so I guess they'll figure it out if I just bring them the sensors and the cats

joe4speed · 10-11-2003, 04:43 PM

Look at the other end of the pipe.
Here is a bad pic of it, my h-pipe is buried underneath a bunch of stuff but you get the idea. It's on the other end right near the flange.
That other tube in your pic goes to your air pump.

Sicy Stang · 10-11-2003, 04:55 PM

So its on the end that goes to the mufflers or? I dont see any holes on them. *sigh*

The part that goes to the air pump can be re-welded or something right?

I should have never taken these things off in the first place. I'm payin for it now 8 years later

The end that the pipes are closest together go into the mufflers, the end you showed in your pics. The other end that's wide apart goes into the headers.
The part that connects to the air pump you can actually use a length of heater hose to reconnect it, I did that 7 years ago and it's fine to this day.

Sicy Stang · 10-12-2003, 06:39 PM

Ok I feel dumb. I found the oxygen sensor holes in the pipes finally. The brackets or whatever were covering them so I didnt see them the first time. Thanks for all your help.

So tomorrow I'm taking the car to Meineke to have them put the cats back on and the sensors. I'm hoping that's all they need to do and my car will pass smog. My smog pump (new) and equipment is all still there. Anything else I should be concerned about? I have a new idle air control valve and the throttle body and injectors were just cleaned a few months ago. I found out my headers are legal so that's good. Car doesnt burn oil or anything. I'm just concerned because that car hasnt had a "real" smog in over 8 years.

mustangman65_79 · 10-12-2003, 07:25 PM

should have no problem, as long as u use high grade octane.

Sicy Stang · 10-12-2003, 07:54 PM

I've always used the highest grade gas on that car.

joe4speed · 10-13-2003, 12:31 AM

I wouldn't worry either, I'll bet it'll be just fine!

Sicy Stang · 10-13-2003, 12:41 AM

Thanks Joe.

Nice website, I love your cat foo

I have two myself
