My 1988 Ford Bronco was occasionally idling erratically. When in park, with the engine running, periodically the rpms would go up and down but then would even out. Recently, when this problem occurs, the rpms will drop to the point of causing the vehicle to stall. Now, it is happening at stop signs and in traffic. Any ideas?

Clean out the idle air control valve/mtr/ISC and see what happens
