I have a 2006 expedtion that the engine revs when coming to a stop.it feels like you have you foot on the brake and the gas at the sametime.the ford dealer has replaced the throtle body and reset the computer.I read on other web site that if you replace coil#6,7,and 8 that would take care of it.does anyone have any ideas?

The newer Expedition are "throttle by wire" This means there is no longer a mechanical wire connecting your accelerator to your throttle body, it is controlled by electronics. This is a very similar situation to what Toyota is going through right now. Take it back to your Ford Dealership and have them properly diagnose the system.
