Don't get me wrong, they do adjust the mixture, but if it gets out of a 
range by +/- 5-10% (depending)  it throws a fault. Then, you gotta find 
the vacuum leak, leaky injector, bad sensor, etc. Since the start of 
OBDII @ 10 years ago, that number is down from 25%. And, like I said, 
their primary job is feeding the cats...
