I got an o2 sensor of an a6 because my a6 is givin me a Code 1
so i went to swap them and they look different.
my car seems just as powerful when i have the CEL
if i put the new one in... is it gonna change performance
and even tho they look different do you think that they will work

 

is yours oem or aftermarket?

 

Also is my car running rich without the sensor working?

 

I'm not exactly sure. i got the car with it in there. the one on my car now is thin
and the one that i pulled off the junker is like 1/2 inch wide.

 

well if it came off a crx/civic it would work...i personally would have bought a new one from autozone or wherever...

 

well i was at the junk yard. just gettin other stuff like gauge clusters and tail lights
and i saw the civic si. some dudes were takin the block but the left the header lyin there
so i just snagged the sensor to get rid of the light.
if i put the new one in there do you think that my car will run better?

 

**** i forgot. the fucknut who had the car before put an integra exhaust on the car. so the o2 don't fit

so if nebody has a teggy o2 and wants to trade for a d16a6 o2 i will be glad to!!

 

Ummm, what do u mean somebody put on a teggy exhaust?? The exhaust manifold for a teggy will not fit on a D16A6, and i believe the 90-91 teggy O2 sensor is the same for the 88-91 Civics, as long as its the single wire version (thats why i say 90-91 teggy).

 

i believe the pre90's kinda fit.... thats what i was told by the guys at the muff shop
because i was having problems with the header seperating from the down pipe
they said thats because i have a teggy exhaust

ok here is my problem
the o2 sensor that i got at the yard has too big threads
my header has a smaller hole by about a mm

 

the muff shop eh? ha well just go to the junkyard with your o2 sensor and start comparing it with others. or go to the muff shop and ask them what sensor you need.what engine is in the car? d16a6?

 

WOW...Did you read the thread at all?
