Sort or a dumb question, but couldnt find the answer after searching on here. So one of the wires from the o2 sensor that is hooked up to my a/f gauge keeps getting disconnected after i resauder it, can i get an oem o2 senor to replace it or does it need to be a specific o2 sensor, btw its a greddy a/f ratio gauge.

 

Solder..

You don't know how to solder?

What brand gauge?

Amazon has wideband gauges for aem around 50 bucks cheapest I've found them.

No a regular o2 sensor will not work. You need a wideband sensor
