Gotta pass emissions I have a good knowledge about cars but im always learning so I need to know where nocs sensor is so I can change it

 

are you talking about NOx or the knock sensor? The knock sensor is screwed into the side of the block, usually around the motor mount bracket area. Im pretty sure the 92's didnt have an NOx sensor. They just used the O2 sensor and EGR. BTW, did you swap a 3.8 into your car or is that a typo?

 

Nah its a 3.1 and thats why I was confused they said I had a problem with the nox I guess so im just gonna get a new egr and new 02 sensor from rockauto and go elsewhere for my emissions think that will do and maybe get a 3 cat

 

Do you have a check engine light come on ever?

EGR will effect NOx. EGR is there to cool your combustion temperatures. If they get too high, thats when you start creating NOx. But there could be other issues causing your combustion temps to be high and creating excessive NOx. BTW, your EGR valve isnt gonna be cheap.

 

Yeah egr is about 150 and the check engine light comes on only when I go above 70 then drop my speed ive been wondering why but it goes off eventually but the check engine light didnt come on during emissions

 

Pull your codes. Get a paperclip, bend it so the two ends are almost touching. Then put them in the two top right spots on your diagnostic link connector. Your check engine light will flash your codes. it will flash 12, 3 times, then any codes you have each 3 times, then 12 3 times again when all codes have been read. It will flash the light in a group of fast, pause, then a group of fast again. Example X,X....X,X,X would be 25. Let us know what codes you have.

 

Alright will do thanks for the tipill post as soon as I can
