99 Altima - Idle Pulsing/hunting - IAC problem?

Like the title says - it hunts constantly from about 1100 to 2000 rpm. It gets a little better with the AC on. It seem to run fine other than that, and it's not throwing any codes.

I took the IAC off and cleaned it, no change. But - shouldn't there be a spring in the IAC? Mine didn't have one, nothing in there but the plunger.

Could that be the problem? Any help is appreciated.
