My car will cut off while at a red light or stop sign, but it will start right back up. It drives fine I just have to drive with two feet in order for it not to cut off. I have changed the fuel filter, egr valve, air filter, spark plug and wires and the first coil.

First eliminate all vacuum or air leaks in the system (very important)

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 carburetor 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.
