i have an autometer phantom a/f gauge. its brand new, i have it spliced in the o2 sensor, when i turn my car on, it works fine, but as soon as i rev a little and pull out, it goes off, it seems like it only works right when i turn my car on and before i start driving

 

have u checked all your connections?

 

yes, and i even put the power and ground to a new source today, same thing, i think im gonna try hooking it up right near the ecu rather than the o2 sensor now, anyone know what color wire i hook it up to on my 89 interga ECU in my 88 CRX?
