Quick question - how many o2 sensors are there on a 99 d16y8? I know there's one before the cat on end of the header but are there any others? I notice my car bogs a little bit at low RPM's and I've done a complete tune-up besides PCV valve and any other o2 sensors I may need to change. So if there is another o2 sensor, Ima swap that out soon. Motor has 178,300 FTL .

 

Two.

 

So I'm guessing the 2nd one is the downstream one (after cat)?

Perfect . Thanks

Actually, it's bolted into the catalytic converter.

 

Same diff lol.

Thanks again .

 

if your o2 isnt throwing a code why would you need to replace it?

your car is probably bogging becuase of other reasons

 

I like replacing things just for the sake of replacing. The upstream o2 sensor was never changed until 16x,xxx miles and the downstream one is still OEM with over 178k, on it. I just like replacing parts.

 

you can replace my broke *** by sending me the money instead of just replacing parts. If you feel the need to spend money, why not upgrade something that would benefit your motor and/or your car. Do something productive.

Replacing a part that has nothing...absolutely nothing to do with your motor performance-wise is stupid and you should have some sense knocked into your head.

 

i wasnt going to say anything but then i saw this


"Stock D16Y8 + Broke College Student = FTL"

save the money for books

Exactly. The dude can send me his old (and still working) o2 sensor so I don't have to pay to replace my bad one.
