i have a 1st gen b16a obd 0 with pwo ecu(virgin) not chipped.

i have some 4-1 headers with the o2 sensor on the header but it's not plugged with the yellow/gray wires. i'm getting no check engine light whats so ever, car's running ok. i was wondering if i can bad mpg running it like this. i dont have until the weekend to fix it, so i just wanted to ask...

 

Are yo usaying your O2 isn't plugged in at all? Aslo, are you not running your 2nd O2?

 

On a OBD 0 engine, you should have 2 o2 sensors. BOTH of them should be 1 wire 02's.

One before the cat and one after.

Yes, it's not plugged in at all. i looked under my header. since i have an aftermarket header it can only use 1, yes i know i can splice the wires, or just do another hole on one of the pipes on the header. I'm just trippin out cause. my car is running fine, no cel, vtec pops,with no o2 sensor connected with the wires, it's on the header but its not wired.
