    so do you have an aftermarket header? Or do you just have a stock header with one of the o2 bungs not filled? Either way, you should run a second o2 if at all possible. Just go to the nearest junkyard and pick up a sensor, you'll thgank yoiurself.

    It isnt good to run just one o2 or wire both into one. You have to have both wires separately for teh engine to run properly. You can either buy a real B16 header or add a bung to your existing one. On teh stock header the bungs are on teh collectors of 1-3 and 2-4.
