i got a chk engine light and it says 2nd oxygen sensor heater wire, would the secondary oxygen sensor heater wire (blackwires) cause any problems for my car if i dont fix it, cuz it keeps my chk engine light on,

does the 2nd oxygen sensor even have any effect on my engine performance or air/fuel cuz i though it just measures cat efficency

ohh i dont have the 2nd oxygen sensor plugged in, well i have no cat lol.

The secondary oxygen sensor is only used to check the quality and performance of the converter.

Regarding engine performance, it will have no affect.

Put a cat on your car. Interstate 94 isn't Taladega.

 

no doubt but what about the code and heter wire wtf is that

ohh i always take the cat of my car, i dont care about air, **** who cares, im getting better mpg and performance, its funny cuz my dad gets mad cuz he works for a shop that makes cats and **** lol
