    Rich or lean

    Can anyone tell me how one tells if a car is running an A/F ratio that is too rich or too lean? If it's too rich, i think one would smell it sometimes, but are there any other effects?

    There will be more smoke come from your exhaust if it's too rich. Also on a carb it will flood it.

    If it's rich you'll have poor gas mileage and you'll smell it in the exhaust and feel it burn your eyes . If it's lean you'll have a loss in power. If you have access to a scanner hook it up and check the air/fuel ratio, 14.7 to 1 is the ideal mixture.

    Hypothetically speaking. In real life when tuning cars, an idle might be that lean, but at WOT the a/f is anywhere in the 12.5-13.5 range.
