It is a factory safety item programmed into the EEC. Keeps engine speed high enough to power all accesories, power brakes and power steering. It is typically 500-600 rpm over normal idle speed. It could be tuned out, but you run the risk of engine stall if you put a high load at low rpm. For example, if doing 50 mph , in neutral, you decide to turn hard, turn a/c on and brake at the same time.
