So I was under my car working on it last night when I saw some wires just tucked up above the heat shield right where the exuast comes off the manifold and then wraps around to the bottom of the car. So I grab the wires and there sits my 2nd O2 sensor. I have a pacesetter header and a 2.5' exuast all the way back to a camaro style muffler with no cat, lucky enuf to have that all on the car when I bought it. I know on my wife's civic, witch has no cat the 2nd o2 sensor was just removed from the clip all together. By leaving the o2 sensor on the clip and exposed to the air what could it do to the car??? Should I un-clip it??? Sould I go to a exuast shop and have them weld in a bung??? Just wondering.

 

i would have it installed into the exhaust with a new sensor. you need that thing i think.

 

You don't have a CEL on? Do you have an aftermarket PCM.

Oh and you should change this in your sig...
KYB doesn't make lowering springs for our neon

 

Cel light had been removed. no aftermarket ecu ether.

Das, I was told that they were kyb's. sorry. What are the blue ones ive seen people say on the other forum that they wish they hadent gotton rid of them.
