02 simulator for b16, do you need one?

hello, i was wondering if you need to buy an o2 simulator for the b16, becuase my check engine light is coming on and it idles and accelerates bad

do you have both o2 sensors hooked up, or at least have both o2 sensor wires hooked up to one sensor?

i have them both hooked up, i ran that 2nd o2 sensor to the ecu

did you use shielded wire? because if not, its gonna pick up interference

no i didn't use a shielded wire
