O2 sensers

[wibilly]

i just went and got one of these modern trucks (1992)yea thats like brand new to me i'm a67-72 guy.well anyway ifound it has had a newer engine installed so no bung in the exuast manifold for an o2 sensor.the way i understand it they were a one wire and in the exuast manifold through 92 then went to a heated(3wire) starting in 93.so i'm looking for advice from somone who knows more than me(thats probably all of you).should i just weld a bung as close as i can to my left exuast manifold and use the existing single wire or put in a balance tube in my newly installed duel exuast and use a heated (3 wire).i really dont wanna spend any money because as with all my vehicles i wanna drive it 30,000 miles and get all my money back.i do realize that i will never get all my gas money back and my fuel econamy is directly related to the o2 senser. yah i'm cheap but i'm not stupid.my question is, will it make a differance in fuel econamy using a 1 wire or 3 ?a freind of mine told me that the bosh o2 sensors are junk andto spend the money for a AC one.what do you guys with experiance on this computer infested junk think aboutthis and what will give me the best fuel economy

I agree it is best to stay away from a Bosch O2 sensor.

A balance tube is not needed for the oxygen sensor, and a o2 sensor should not be located in the balance tube.

A single wire sensor is ok if you put the oxygen sensor very close to the engine.

If you install the oxygen sensor a couple feet from the engine you should use a heated sensor.

If you want to keep the cost low, go get what you need from the U-Pull-It.
