Ok it seems like my 02 sensor doesn't want to go above .89 volts, and I was even killing my car with too much fuel(black smoke/bogging-rich knock). How high are these sensors supposed to go. Also on high throttle with 2000-7000 set at -25 my o2 reads .76...I'm guessing problem. Is the voltage problem a sign that my o2 is shot or what?
