I am putting on the 2.0SS dp on my 07 2.2 and I noticeed I have 2 oxegyn sensors 1 before and after the cat. the ss dp has only one after the cat. Which connector do I plug the new oxygen sensor into? and waht do i do with teh other one.

 

You're sure you don't have SAI?

 

I dont have sai b/c it was not on my factory airbox when I put my injen cai on. i am so confused

 

the pre-cat o2 sensor bolts into the exhaust manifold, not the down pipe.........so the down pipe should only have 1 o2 bung in it.

 

No i dont have any o2 sensor on my header. idk what to do

 

you might want to take a second look.....

 

took second look and no 02 sensor on the header

 

should be under the heat sheild. right next to the flange

 

Guys on the 07's the 02 is deleted from the manifold and is before that cat on the downpipe.

 

Yes exactly so I have only 1 02 sensor hooked up right now

 

so you do not have the pre-cat o2 sensor hooked up?

 

No i did not hook it up b/c there is no place to put the oxygen sensor.

 

then your car will pretty much go into safe mode, command a rich fuel trim and your gas mileage will not be as good
