My engine hava 300 miles since is just rebuild and everything worked good for two weeks till suddenly at a stop sign the engine die when I hit the brake loosing also power steering wheel. Things goes a little bit better when the AC is off but as soon as is on again boom the problem shows up again. I have tried fuel filter, new spark plugs wires and also cleaned and check with the ohmmeter the two coils of the idle control valve but nothing. Any suggestions. Please. Thanks

I would first remove the EGR valve and make sure no carbon is preventing it from closing all the way.

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.
