Well I had my car dynoed a few weeks ago and it seems that my two front O2 sensors are not working. The rears are shut off on purpose due to longtubes but I can't figure out what's happened to the fronts? They are showing really minimal voltage, like .1 volt, even when at high rpm. Is there a relay that controls these specifically? I highly doubt both O2's would go at the same time. Do you think changing them might help? They're $140 a piece so i don't want to change them if you guys think it could be something else. Any ideas? no fuses are blown.

Are you getting error codes? Is the engine running rough? It certainly is feasible that the excessive heat from the headers could have shortened their life. Just replaced both my front ones with Bosch units, which were $54 each at Auto Zone . . . sure cured my issues.

if you have to get new ones get it through randy stinchomb on here for $50 or theres another guy at a dealership that will give the same price.
