I have a feeling my car runs a little too rich, but I don't know how to check it. Is there a method or a guage I could buy that would tell me the mixture? Also, is there a way I can adjust the air/fuel ratio without a fuel controller? (I've had a super AFC on back order for like two months now, I'm so sick of waiting).

?

 

couple of ways to check... either get an a/f guage, or use a voltmeter to check the voltage of the o2 sensor (forgot the specs...)

both use the o2 sensor for checking but not very accurate as i know...

TII no? i don't think there's much you can do without a controller of some sort

 

You can also buy an exhaust gas temp. gauge (EGT). Theyre more accurate than your typical a/f digial gauges.
