Answer
stalling is usually caused by a blackish residue buildup on and around the throttle plate area and also on the Exhaust Gas Recirculation (EGR) valve and within the EGR piping.

You need to perform a cleaning of these areas using a spray can of carburetor cleaner or similar product.

You will need picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture. I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information.
