not a bad price either

 

you can just get a set of MIL eliminators that you could buy for $10 a piece or just build yourself for about $3

 

i have those same ones, ill sell you for $40 shipped, brand new

 

I take it then that you didn't get the chance to use them? If you were to have had that chance what would you have expected under light driving versus moderate acceleration? I know that the O2 sensors are not used by the PCM during heavy to WOT acceleration. Any idea on mpg impact for cruising? It sounds like the PCM would have virtually static O2 data regardless of acceleration short of heavy.

 

just for the rear o2's... just keeps the CEL off. wont affect anything else

 

Oh, ok. I thought they might have replaced the front O2's. Big difference.
