I've got a 1998 Navigator. When I turn the ignition is idles very low and sometimes dies. It runs great in drive or when I accelerate and runs on the hightway for hours. But when I come to a stop, it dies. Any clue what's causing this?

The Idle speed {air} Control (ISC or IAC) dirty or inop... is one possibility.
My wifes 89 thunderbird did this so I read the trouble codes and it said it was the EGR valve. Sure enough, the diaphram in it was baked and had holes in it.
