My air/fuel guage is still reading between .5 to 1.4 volts. Could an exhaust leak after the o2 sensor cause it to mess up. I don't think I have a leak before, but I'll double check. Anything eletrical that could cause this? I'm gonna try somemore stuff and see what happens...

 

try a different ground and yes it will really mess the readings up if there's a leak.
