hey i have the aem uego guage, and it jumps around, not alot, but alittle from about 13.8 to 14.7 or so at idle, and its a wideband. our cars, and most others id guess, af just jumps a little becuase its constantly changing the a/f right.

ye idle and partial throttle have the same jumpy a/f reading usually, but when you punch it is when it changes and jumps into the 12's
