1991 Honda Accord 4 cyl Front Wheel Drive Automatic 275K miles

My 91 Honda Accord idle hunts when hot and in park. It surges constantly between 900 and 1700 RPM. This idle hunting is not affected by A/C compressor engagement. I also have a tcc issue and am unsure if it is related to the ide problem. My TCC lock-up engages and disengages rapidly at a rate of approx 1-2 seconds. (Ie: @70 mph---2700rpm to 3100rpm.) On-Off-On-Off-On-Off. This seems to happen less frenquently after 30 min of driving.
