So i have a 86 pick up with a 93 22re.
The most recent "bug" ive ran into is my local exhaust guy, Junction City Muffler, said i should be running an o2 sense my trucks running really rich and lacks power when i get on it.
im running a headman header and full flow exhaust with a 40 series.

i tried to get a o2 for the 86 and i got a 1 wire...well the o2 plug has 4 wires

white/red
pink/green
black
brown

so i got one for a 93 and it was $103 but it doesn't fit and the wires are blue black black white.

any advice would help and don't say read cause i have.

 

first and formost take that o2 back and get your money... their are two different kind and Ive seen the one your refering too on 89 models as well.. 2nd go to amazon and order your o2 from their... thats half the price for your o2 sensor... mine at oreilly was like 110 or so i paid 46 w free shipping.. if you need to reference to part numbers try matching up the plug you should get from oreillys then inserting it into amazon search bar... worked for me and got new o2 sensor on... also you may want to check those bolts holding it on they are usually rusted away and will require some persuasion to remove... it was a pita gettin mine off... peneblaster works wonders along with a grinder if it dont wanna work with that... may wanna find some replacement studs as a backup if that fails altogether like mine did...

 

Thanks but that didn't really help. What O2 sensor goes to the white/red pink/green black brown plug? There isn't and exaisting sensor seeings how it has a header and exhaust I didn't think a o2 would matter well it does then I traced the wires down.

 

OX (black wire) is the oxygen sensor signal E1(brown wire) is ground. The other two wire are the heater circuit white with red stripe is positive and pink with green stripe is negative.

 

Not trying to be rude but most people dont want to answer this because Its quite simple. Searching for things helps its not difficult. Heres your freebie


Thats your 93 with four wires. Make sure it fits it has a guide to make sure. And a picture to show how many wires. I would look up your make sure that the original part numbers for your sensor match up

 

I already found that on amazon but the wires are blue black black white.
I have that same one but Bosch
Will that o2 plug into the current plug on my harness?

 

Here is a color code chart for oxygen sensors http://4crawler.com/4x4/O2SensorWireColors.html

 

Have heard bad things about the Bosch, get a denso. When I was searching through the thousands of o2 threads kept reading our trucks don't like something about them

 

I agree the problem with the bosch is it's tip is not as long as the denso so it doesn't get in the exhaust flow as well. Some people run them without problems but alot of people have had check engine light problems with them.
