the 89 rc has picked up a new trick somewhere. When it is warm or you shut it off and run in to a store, come back and restart the truck it revs real high then goes back down to normal. Any ideas. Still has everything stock on the motor. I doubt the o2 sensor has been replaced yet (318 auto)

revs real high meaning how high? like in the 2-3k range or into the 6k range?
