O2 Sensor reading bad
I have just finished my rebuild and went to get a tune on the new set up. My tuner noticed the passenger side O2 was dumping a ton of fuel in the bank. I replaced the O2 and took it back to get them turned on. He said it was do the same thing. I am getting voltage to the sensor. What else could cause a new sensor to still read bad? I am lost..
