ok so i finaly hooked up my air/fuel gauge yesterday and i know it isnt suposed to do what its doing, when i start it it goes from lean slowly over to rich then just goes back and forth and when i drive it keeps on going back and forth the only time it stops at a certain one is when i get on it and it goes straight to rich and stays there till i let off the gas, i hooked the one wire to the ignition fuze in the fuze box, another into the engine block ground and the final into the front o2 sensor wire (white w/red stripe) on top after the conection from the o2 sensor but before the 2nd connection. what did i do wrong??? i know it wont give a good reading unless you have a wideband o2 sensor but it shouldnt act like this should it??
