car stalling on 2003 Ford Windstar

replaced alternator, adjusted air control valve
and cleaned egr passges x 2. still stalling when coming to a slow stop

Asked by for the 2003 Ford Windstar
first of all, you cannot adjust the iac valve. you can adjust the throttle body stop screw but do this only after cleaning the throttle body. otherwise, you may have a vaccuum leak causing the stalling issue.

There are 2 aluminum rods that control the air and gas mix. These rods are only held in place by little plastic clips. I found the rods laying on the engine. Replaced them with new clips and the stalling went away. I am not a technician so it's not a technical answer. Hope this helps.
it might be the RPM controller this what they told me when i had the same problem after replacing that it was good first i was thinking it was a spark plugs but then turned out to be a RPM Controller hope this help yours might be something else just check that
