Ultragauge has been on and off sending a pending code P0134 .

Got almost 80k miles.

Noticing a little roughness in the idle now.

Anyone have suggestions on the best 02's I can get in this day amd age for the truck? I would assume I should change all at once.

 

Atlantic British has the O2 sensor kit on sale now for $219- Best deal to replace all 4

 

I put Denso's in mine and they've worked great.

 

Walker, they work and they're not expensive.

 

Opinions vary on this, but I see no reason to replace the downstream O2s if they are not throwing codes. Remember, they have absolutely nothing to do with how well the engine runs. They are there to measure how well the cats are performing only.

As for what brand, I will try Walker next time I need O2 sensors for my DII. I have always used Bosch, but I have had a few be bad out of the box, and that has been reported by others also.

 

So I noticed the ones on AB are Walkers.

I found the walkers on rock auto for 25 and 40. (Fronts and rears).

I assume it's the same model

 

I've had dead o2s out of the box with bosch ones at an alarming rate. Not sure what the deal is.
