IS this where the 2nd o2 sensor is suppose 2 be

thats with the obx 4-1 headers installed and all the 02 sensory holes were there.
OR do i have to reloate the second o2 sensory a bit farther down?

if you have a cat put it after the cat if you dont put it there

The headers do come with two o2 bungs. However they both would read the same thing. The second o2 sensor needs to be placed after the cat.

thats right. if you dont have a cat-converter the check engienge light will go on if you remain in idle for to long. will have to relocate further down the exaust.

Yeah the CEL isnt too bad by itself but unfortunatly this CEL will cause the car to go into fail safe mode. So if will be very sluggish.

that is tha place of the 2nd o2 sensory and no i donot have a cat-converter just a glass pack my check engine light first did go on once i changed tha hearders then after i changed tha o2 sensor it was all good.
so should i leave the o2 sensor where it is ? or move it a bit farther down.?


the arrow in tha pic is the 2nd o2 sensor just 2 make it clear

AllEyesOnME

can any one confirm this cuz i going 2 get my new muffler installed friday should i reloate the o2 sensor farther or leave it wher it is.

If you don't have a cat, then you don't have to move the O2 sensor because it will read the same thing either place.

Mad-Machine

which on a North American Tib will get you a check engine light because the comp needs to see a difference between the first and second O2 sensors.

Exactly what Mad said. It is a pretty basic setup. 1st o2, cat, 2nd o2.
