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.

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.

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.

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