STOPS WHILE RUNNING

2003 Ford Taurus • 3.0L V6 Automatic • 138,000 miles

If I come to a stop such as a traffic light my car Stops and I have to turn it off than back on and it runs. For it not to stop sometimes I tap on gas so it keeps running. When it stops I never lose any power like all lights on Radio on but the car Stops running. What the problem could be?

First eliminate all vacuum or air leaks in the system. 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.
