Re: 2001 Windstar Rough Idle / Misfire
Mine is a 98 and there was a change made after 1999, however this may help you.
Check the 2 IMRC bellows on the left side of engine behind alternator.
Two things to look for there
1. leaking vaccum on bellow (Remove vaccum line hold the bellow line opening with finger and try to move the butterfly - you will feel resistance if bellow is good and no resistance if there is a leak) and
2. the plastic bushing with link which connect the IMRC bellows to the butterfly.
If this things above is fine than it can be the blocked EGR ports under the Intake manifold.
Thank you.
