my 04 came with a lunar a/f gauge (bought it used) it has no visually noticeable mods,but my question is, at first start up it shows real lean then after warm up it shows rich. It just seems odd, every other car ive had a gauge in was the opposite. could it be wired wrong? :shrug:
a/f guage ??

- Start date
i dont know for sure, i know its running rich by the smell of things. I have come to the conclusion that there was at least a cai on it due to scratches around the bolt holes near the stock air cleaner housing, and it has flows ont it. I have only put 140 or so miles since i bought it.
the car should do everything it can to keep itself at 14.7:1 unless you're at WOT and the pcm has gone open loop. then it should go to whatever a:f ratio your tuner commands.
