so i got a new gauge and installed my A/F gauge and made sure all the connections were good, i have it ground, i have the o2 sensor from the gauge going to D14 on my P28 ecu( which is the o2 sensor signal) and my power connected to the radio/ cigarette lighter fuse, when i turn on my car it all goes well but after a few seconds the gauge dies from reading rich to reading lean and then it turns off. i dunno why it does this, is my gauge just not getting enough power? or is it on the wrong ecu wire. if anyone has any suggestions or has been through this. PLEASE lemme kinow. thanks

try some troubleshooting.... switch to a different power and/or ground and see if it still happens

suprame, do you know if its better to get the signal straight from the sensor or from the ecu like you, because i just did mine from the o2 sensor and its reading like 1-2 bars into the lean side. my cars alll stock so it shouldnt be.
