I have a 2000 Ford Crown Victoria. For a couple of months, sometimes when I am slowing down, the idle speeds way up, like I'm applying the throttle, but I'm not.I'm braking! The engine's running very fast, and to slow it down, I have to put the car in neutral when slowing down, the engine speeds way up, like I'm applying the throttle, but I'm not. I have to put the car in neutral for the engine racing to stop. The dealer changed the IAC but that did not work. Now they say they have no idea what the problem could be, that it does not return any faults or trouble codes, and it does not act that way when they drive it.
