Engine won't idle when at stop signs. After accelerating the car will die at any speed and then restart while still rolling. Have checked electrical connections .. Need help?

You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.

Is the IAC an expensive part. Would that cause the higher speed cut out?

I was under the understanding that it stalled only when you let off the throttle.
