underneath the intake tube is a screw,you need a long flat head screwdriver,adjust that,see what happens. youll see it if you look hard. but thatll usually fix it.

My 94 FD has done the same thing ever since i had the recall done for the fuel lines/fan modification. It will idle for 1 minute or so fine, then for a period of about 1-2 minutes, the rpm's go from 1-2.5k or so about 10 seperate times, each up and downswing lasting about 5 seconds. Not sure what to do really... car runs fine once it gets goin.
