LOW IDLE WILL NOT ADJUST

1996 Nissan Altima

Engine Performance problem
1996 Nissan Altima 4 cyl Front Wheel Drive Automatic 184, 00 miles

I have a 1996 altima that has dropped into low, rough idle and will not adjust up or down or idle well. The headgasket was replaced recently. The O2 sensor, crankshaft positon sensor, radiator, water pump, thermostat and idle control valve have all been replaced. After the water pump was replaced it dropped into low idle and the rpm gauge quit working. I can move the EGR diaprham and notice it drops when I do. The MAF is the original. The ecm self diagnostic found no trouble codes stored. It has power when moving but will sound like its going to die out at a stop. Any ideas?
