What do you do when your car is stalling?
The Fix: Clean or replace fuel injectors. Even after the engine has run long enough to become warm, the idle speed does not come down to normal but continues to idle at a fast pace. You really notice it when you come to a stop, after which you have to push hard on the brake pedal to keep the car from moving.
What causes a car to stall at a stop light?
An engine that stalls when you reach a stop light or while idling may point to a faulty idle air control solenoid (IAC). The computer uses the IAC solenoid to bypass the throttle valve and inject more air, depending on engine operating conditions.
What causes a car to stall on a cold start?
It also manages the idle under changing engine loads, like when you kick on the air conditioning, turn on the headlights, or turn up the radio. When the idle air control valve malfunctions, you may experience a rough idle or the vehicle may stall entirely. This is especially true on cold starts.

You take your foot off the gas pedal to apply the brake, but your engine begins to idle very roughly, and then it stalls.
