Vince,
no hunt at idle is 'bad'. You are pushing too much fuel through the injector at the LH's minimum fuel injector pulse width. The system requires an a/f which 'hunts' except at WOT. Possible problems of continued running: 1) reduced piston bore life 2) reduced wallet thickness (poor fuel economy) 3) clogged Cat converter. You need to detune the output of the AMM (resistor or op amp circuit) or reduce the fuel pressure, or both. The A/F should also 'hunt' at partial throttle as well. try to see the whole engine as a system which must be tuned to deliver HP and driveability. Too much of any one thing can destroy the balance and other things must be changed to optimize the system at this new point. good luck
