O2 sensor, does what, really? 200 1984

posted by  someone claiming to be John M on  Tue Oct 20 17:09 CST 1998 [RELATED]

I know that the O2 sensor will cause the conputer to enrichen or lean according to what it detects in the exhaust, but is it for performance or the environment. Does performance suffer when the O2 sensor is bad? What is it really for. Also, what are the symptoms of a rich or a lean (ie air leak beyind the AMM) running car?

Thanks,

John M
