When I stop at red lights or stop signs my stang shakes and or acts as though it may shut off by itself. I have changed the fuel pump, fuel filter, new motorcraft plugs , had all the coil packs checked changed one, new intake manifold, new air filter, cleaned the mass air flow sensor, and still no luck. Guys help me out gimme some things I could do to help I just want it to stop the shutter at idle everything else is fine.

Thanks

Check for a vacume leak in your hoses. I had the prob, had a hole in a hose that was connect to the left valve cover. Open your hood and listen for any whistleing noises. Hope thats the prob, cheap fix. Is your car throwing a engine light??

if you find a leak in a vacume hose, u can get them at auto zone, they can cut them for ya. Just take a knife if u gotta do it at home. Just feel around the hoses with your hands. Some say to spray engine with water till u see some bubbles, but i think it's easier to hold the hose, and go down it till you get to the base and try the next.

Thanks man i will try to find the leak , how about I just replace all the hoses?? kill all birds with one stone huh? , tell me how many are there?

I personally dont know how many there is. You should go to a auto store and buy several feet of the hose size you need.
