i just did a jdm b16a swap in my 88 crx and it has been drinking the hell out of gas, i only have one o2 sensor and every other b16 ive seen has 2. so someone tells me to mount a second o2 sensor and run the wire to the ecu...is this correct? if so, where do i mount the o2 sensor and where do i put the wire in the ecu??
