I am trying to install the Air/Fuel Glowshift narrow band gauge on my 03 Sunfire. I have it the green sender wire going to the purple wire (16) on the PCM. All the gauge does is hop around like crazy and make my instrument gauges stop working. Why and how is this? Any help would b greatly appreciated
as for what the a/f gauge is doing: thats normal operation. as it's useless.
