Welcome to the forum
On a fuel injected engine the "gas pedal" is actually an "air pedal"
On a Carbed engine extra fuel would squirt in when you pressed down on the "gas" pedal, it was done by the accelerator pump
On fuel injection the computer adds extra fuel but by calculating increased air flow when throttle is pressed
So best guess is you have a vacuum leak, could be TPS(throttle position sensor) but you should also notice that when warm
When an engine is cold it needs to be Choked, which means it needs to run Rich, if there is too much air(lean) it will stall
