ONLY STALLS WHEN COMING TO A STOP OR SLOWING DOWN

2000 Ford Expedition • 188,000 miles

My 2000 ford expedition keeps stalling and seems to idle real high. When it stalls it starts right up it only stalls when im slowing down at a stop or red light or either when i'm parking or making a slow turn but it starts right back up. I changed the spark plugs, that didnt help. Any idea what this could be?

No codes that I know of. Can you tell me what an iac/icv is?

AS he first mentioned, it could be an issue with a vacuum leak. On the rear of the throttle body is a vacuum line that has a 90 degree turn in it. They have been known to dry rot and leak. As far as the Idle air control valve, remove it and make sure the pintel is moving when the key is turned on and off.
