Ok well I installed my AM Lunar A/F gauge a few weeks back and everything was working fine until tonight. After I started the car up I noticed the gauge did not move like normal but stayed on one bright yellow bar. Sometimes you could notice some of the other colors light up faintly but that one bar always remained. I dont think it is in my connection because I checked them tonight but I may need to do it again not really sure. I connected to the Purple wire coming out of the O2 sensor before it plugs into the harness on the driver's side. I have no idea what is goin on though and could really use some insight.
Thanks, Malcom

Try reconnecting the wire and also even cutting power to the guage completly and then reconnect power. I would say its either a bad connection or a bad guage. Maybe you'll get lucky and power cycling it and reconnecting it will help.
