Engine Idel

90 Jeep Cherokee Limited 4X4, it idels fine for a muinte then it goes to 1200 to 1500 RPM and it may stay there after warm up or come back down. I've done replace the stepper motor, Air sensor, MAP sensor, and unplug the coolent sensor and none of this has helped. My next step is the ECU.

Does any body have an idea what it may be???
