O2 Sensor Replacement with pics

[Soldier777]

Ok so I narrowed down my rough idle to an O2 Sensor bank 1 sensor #2. There are 2 banks and 4 sensors. Bank 1 refers to passenger side Bank #2 refers to drivers side and Sensor #1 is I believe After 1st set of cats and sensors #2 are after second cats.

here are the tools I used

I was lucky and did not need pb blaster fortunately it came right out. Here are the pics

Plug for electrical:

O2 in exhaust:

old vs new

so as you can see it is pretty easy to do.

did you put antiseeze on the threads?

 

[Soldier777]

it was already there when I bought them

Just did mine last weekend. A word of advice don't buy the socket from NAPA, I paid almost the same amount for the socket as the O2 sensor. I figured out why Advanced Auto was sold out, $13 at Advanced $29 at Napa.

ohh wow mine was only $9 at oriellys

 

[KWT2000]

damn i got mine form snap on for $14

notice a difference after?

Mine idles a lot better now and of course my CEL is no longer on.

Toms I wish I had looked under the truck before I opened the socket because that's exactly how I did mine 7/8 open ended wrench.

notice a difference after?

night and day truck runs perfect no more rough idle no more loss of power and sputtering.

problem is now i think i had a bad wheel baring...

 

[alaskanexpy]

how many miles you have on the stock o2's?

 

[Soldier777]

80,000.... just turned 80k about a week ago

was your sputtering under hard acceleration? I went to class once from from car quest auto parts and they talked about O-2 systems...and how that they should be replaced at or around 50k in order to keep accurate readings...

It was sputtering all over the board, hard acceleration just cruising and even just idling it was acting weird. The biggest problem I had was that it was so intermittent that I wouldn't throw a CEL. After about a week of driving I finally did and was able to figure out the problem.

you can see how bad it was in the picture so 50K might be true.

damn, i was hoping you would say alot more miles lol i have 76k on mine. it runs very smooth no codes..ect but they say the o2s fail slowly over time and it effects performance but you dont notice it because its a slow degrade.

Soldier...am I missin something..I dont see any picture??

 

[Soldier777]

on the first page i am holding the new and the old side by side.. you can see how worn the old one is

 

[BakerEdition]

[Soldier777]

[BakerEdition]

How does it run Now?....one more question...it looks like you got new pipe...where did you find the fitting that the O-2 threads into?
