I just reserched this for my 1988 Ford Festiva Vacum and pray it helps you. Mine is now seeming as a component failure. causing idle and low end fuel delays...
Did this get resolved? I ask because I'm having the same problem. I think it's because my idle won't pull down once the car has warmed up.
High mileage Festivas of the carburetored years have a tendancy to wear out the throttle plate shaft which causes a vacuum leak at the base of the carb where the shaft enters. this will cause rough running and failing smog test. If you can grab the throttle shaft and wiggle it back and forth, then this is the problem. Napa sells a rebuilt carb with new throttle shaft bushings to remove the vacuum leak problem and high idle, lean mixture, fail smog..
