Idle is alittle Rough

I have a 1990 Camaro RS with the 3.1 V6 auto in it.

The car starts up no problem and runs good while it goes through the warm up process. The only time the idle gets rough is when it tries to set idle at 550-600 rpm. At this point it sounds like it wants to stall.

The engine has been rebuilt and the heads reworked. The car has new plugs, distributor, wires, IAC, TPS, fuel pressure reg, alternator and fuel pump.

I did an OHMS test on my injectors while they were cold and they all showed between 12.8 - 13.0 ohms. I searched around and some people are getting 16 ohms so are mine ok?

Thanks!
