To much air

Check your fuel to air mixture or system. My engine was doing that its because i had to much of an air intake. When i started to take care of some of the air intakes, my engine stop stalling at idle. That's just one thing to look at on your stang. What mods have u done?
As the advice from Jack-off unless u can afford a Skyline GTR-34 OR NSX Acura go import. Other than that u can build your mustang to eat rice!!!!........burners.....
