Try shifting to nuetral at stop signs for now. Will it keep running in gear with you foot on the brake? How about with the parking brake? You may have a simple vacuum leak at the brake booster.

I doubt the two problems are related.
The computer uses an idle speed control valve to regulate idle speed. The valve controls the amount of air entering the intake.
You should have a check engine light on and also a stored trouble code for the valve. It could also be a problem with the throttle plate in the throttle body.

Check for vacuum leaks.

Have someone feather the gas pedal while you listen carefully to the engine. If the leak is bad enough you'll probable hear it.
More than likely, it's either a vacuum hose or the o-rings under the intake manifold.

Hope this helps!

1992 f250 occasionaly surges and dies when i stop at lights


there is a pressure feed back sensor going bad all the times
also check the two hoses connected to this sensor for crack or blockage
check the pipe that goes to the egr valve for crack
it won't hurt to pull the egr valve back out to check to see if there is any thing cause the valve to stay open

1994 Ford Escort dies at stops


I had the same problem a year ago. I problem was that the intake manifold gasket had a small hole and it was causing the computer to constantly change the air to fuel ratio. The constant changing cause the engine to die at stops.
