I have a 2.8L V6 carbbed and i cant finy my oxygen sensor! its not any where to be found.....pics would be totally awsome

car is an 83 camaro berli

 

I once had a 84 2.8, the o2 sensor was in the exhaust manifold on the passenger side if I remember correctly.

 

It is in the passenger side exhaust manifold if I remember correctly.

 

checked it dude......nothing....its almost like there is none... This is my last chance at getting some fuel milage cause my v6 is taking 1/4 of a tank to get me into the city and back and i live only 30 kms outside of the city

 

Get under the car and follow from the manifolds to the muffler, inbetween there SOMEWHERE is the O2 sensor

 

well, here's a thought. was the car originally sold in canada? if so, you might not have an O2. do you have wiring going to the carb?

 

Good call, '85! I think we had one of those pop up here once.

 

man, i really need a picture or something....what wiring for it from the carb!?!? what color is this "phantom" wire thanx for the replies though

 

if you can't look at the carb an see a wiring harness to it, then you don't have a computer controlled carb, which means that you don't have an O2 sensor.

From what i understand, and TomP seems to have confirmed...1985 was the first year for computer controlled 2.8L V6, which means taht you don't have an O2. If you did, it's not gard to find, just after the y-pipe joins the 2 banks together. there is a single wire connected to it and it is just before the CAT.

 

Lol I looked for ages for mine on my LG4. Then I realized it didnt have one.

Maybe someone removed it?

 

Computer controlled 2.8's were used first back in like 1980 or so, BUT I remember a few posts way back where Canadian F-bodies did not use feedback carbs. If the carb doesn't have a mixture solenoid on it, then it isn't a feedback carb and shouldn't have an o2 sensor.

 

just as an update on information. I saw a federally certified 1983 carb'd 2.8 yesterday and the O2 is in the passenger side manifold if equipped. You can look right down and see it. Chances are that you don't have one since it would be painfully obvious if it were there.

 

they still call it "mileage" in nations that use the metric system?
shouldent it be kilometerage?
