Idle Mixture Ratio Adjustment

Ok, here's a question for you Z31 owners. Have any of you messed with or had to adjust you idle mixture ratio via the adjustment screw on the MAF? I'm trying to get my idle just right, and when I check my idle mixture as per the FSM states. Warm up the car, make sure diagnostic selector on ECU is fully counterclockwise, turn off car unplug TPS, turn car back on, make sure O2 is functioning and check the two LEDs on the ECU. It says the lights should be blinking simultaneously if your idle mixture is correct. Now does this mean that the red and green lights should be going on and off at exactly the same time, or does it just mean that you're good as long as both lights just happen to be blinking?
