Ok so i got and a/f gauge a long time ago and when i bought it i got it for dirt cheep cause it was damaged so when the guy put it in he said it wouldnt work well i got currios today so played with it. I moved where he had it... off the ecu.. to the actual o2 sensor and i actually got some reading from it. Well it wont read right, like it will jump all over the place like its not gettin a good connection. I tried just wraping the wire around the bare striped o2 wire and then i bought these little connecters. Neither one of those ways worked but if i wiggle the wires, that is when it will jump around. any help will be great thanks guys
