I have 99 dx. It has 2 o2 sensors on it. I tried pulling a header of 95 ex and i t only had one o2 on it. My car ran but then would shut off. I am planning on doing a mini me swap within the next two weeks this besides the point. But I dont understand how you can use an aftermarket header on my car. I mean there has to be a way. I have seen a lot of those cheap headers ad on ebay (i am not going to buy from there though) they all claim you can use them on dx model. Yeah they do have 2 o2 sensor oulets but the one is really low and in the end of the header. Does anyone know how to eliminate or avoid the other o2 sensor?LIke i said i am doing the mini me soon and i want to run a header when complete. help

 

You need an O2 Simulator for that.

 

ok so i got a 02 sensor simulator. In the directions it says to hook the o2 sim. to the bottom sensor. Well the header i have only has one o2 sensor on it. What do i do? Do i hook the o2 sim. to the bottom sensor and plug it back into the o2 outlet on the header which then would leave me with one missing o2 sensor? Will this work or is there some other way? I dont understand this situation. Please help

 

OBD-2 is a PITA. You need to find a header with two bung holes (hee hee). Sell the one you have and get one, ooooorrrrr, go to you local muffler shop and have them weld in one more sensor bung. No biggie.
