I may replace it cause it is not reading right, i disconnected it. Will connect it back this week and check it out the problem started right after i had the oil changed so maybe the guy pulled on one of the wires and disconnected it i get no check engine light but i get no reading from my air/fuel gauge it stays on the rich side. I also forgot to mention i was using an EFIE to lean out the mixture and it worked great(was still in a test stage) so i removed it once the o2 stopped reading. Without the EFIE controling the mixture my spark plugs looked brownish and with it on it was leaning to a lite brown almost getting to white, but not all white just like a little dots.
