First thing is to check for any split vacuum pipes around the intake manifold, even the smallest holes can cause hunting.

Best to mention any mods etc. and what model.

they do the bounce thing if the TPS is out of whack with factory ECU
if FC,, bridge the set coupler near the coils
( green plug 2 pins late, 1 pin early FC  [ earth it ] )
and then calibrate the TPS

( the set coupler bridge is to stop the idle control interfering while you adjust )
