Strange Idle
My 90 Renix Cherokee will idle at about 800 for 20 seconds then drop to 3-400 for 5 seconds and go back to 800. It just keeps cycling.
Is there anything i can do about this?

It sounds like your i.a.c,idle air control. remove it and see if it maybe it is stuck,It could also be something else that is causing it to adjust,like your o2 sensor.
