Hey guys, this is actually just a general question about O2 Sensors.

So before I actually knew the difference in O2 sensors, I put a downstream sensor in the Upstream spot, would that cause the car to run a little sluggish? Like its holding back power?

 

Your two sensors are the same. Shouldn't be an issue. I suggest using OEM stocker replacements if you didn't already.

+1. Oem is the way to go on these. Autozone tried selling me bosch twice, the first time i tried installing two different ones and they wouldnt fit correctly...and so i tried the oem and its been in there for a year and a half. Never making that mistake again.

 

I bought Denso brand sensors from Amazon. They were cheap and worked great!

 

Mine work great, have just been having a problem since we replaced the o2 sensors and the CAT. Just kinda being sluggish all the time now. Ugh (btw not for my D, for my wife's honda) just knew you guys would clarify on the o2 sensors. Thanks..on to the next thing

 

I use Desno or you can use NTK, either are great, but stay away from anything else in my book.

Could actually be the CAT is too small. Did you replace it with a OEM or aftermarket version?
