Switching from a 3 wire to a 4 wire(heated) O2 sensor
I recently converted my '85 GMC to TBI and installed headers. It runs terrible in cool weather, and the original oxygen sensor is mounted in the bottom of the header. I've been told that it needs a 4 wire heated sensor, but I don't know what to ask for. Is there a kit to do this, or will any 4 wire sensor work? I also need to know how to wire it. Has anyone done this before?
