Can anyone tell me why my air/fuel ratio gauge has more then 2-3 leds comeon, before i had eletrical problems which was grounding problems, my air/fuel ratio gauge from autometer use to stay in the rich and 1-3 leds came on but since i fixed it, about 5-7 leds light come on, it seems as if the whole stoic. range lights up as i step on the gas and when i get in to boost, the last 3 leds turn off the stoic. and the first 3 leds come on in the rich side. does anyone know what might be causing this?
