oxygen sensor

does anyone here know how much this sensor is for an ea, just after testing it i realised why it blows big clouds of fuel out the back.
having biggish injectors doesnt help either too lol.

so what are they $100ish new?
i dont think id buy from a wrecker, not for a sensor.

thanks guys.

to test em, look at the 3 wires coming out of the plug. there should be 2 fattish ones, there for a heating element inside it, and i thinner one. make a slit on the thin one and put a multimeter on it and check voltage.

lean is low voltage 0-0.1
rich is high voltage 0.8- 1 volt

mine is sitting on 0.01 volts all the time, which makes the computer think its running lean, so it pours in more fuel. hence the big black spots on my drive, and clouds behind my car.

also it should read .85 volts for the first 40seconds just after starting. not sure why that is.

btw got a 02 sensor and temp sensor ordered at work today, cost $74 very happy!
